In addition to use on desktops for personal scientific computing, Octave is used in academia and industry. For example, Octave was used on a massive <a href="Parallel_computing" title="Parallel computing">parallel</a> computer at <a href="Pittsburgh_Supercomputing_Center" title="Pittsburgh Supercomputing Center">Pittsburgh Supercomputing Center</a> to find vulnerabilities related to guessing social security numbers.<a href="#cite_note-24">[22]</a>

<li>Octave uses an <a href="Interpreter_(computing)" title="Interpreter (computing)">interpreter</a> to execute the Octave scripting language.</li>

<li>Octave is extensible using dynamically loadable modules.</li>

<li>Octave interpreter has an <a href="OpenGL" title="OpenGL">OpenGL</a>-based graphics engine to create plots, graphs and charts and to save or print them. Alternatively, <a href="Gnuplot" title="Gnuplot">gnuplot</a> can be used for the same purpose.</li>

<div class="mw-heading mw-heading2"><h2 id="Octave,_the_language">Octave, the language</h2></div>

The Octave language is an interpreted programming language. It is a <a href="Structured_programming" title="Structured programming">structured programming</a> language (similar to <a href="C_(programming_language)" title="C (programming language)">C</a>) and supports many common <a href="C_standard_library" title="C standard library">C standard library</a> functions, and also certain <a href="POSIX" title="POSIX">UNIX</a> system calls and functions.<a href="#cite_note-26">[24]</a> However, it does not support passing arguments by reference<a href="#cite_note-27">[25]</a> although function arguments are <a href="Copy-on-write" title="Copy-on-write">copy-on-write</a> to avoid unnecessary duplication.

Octave programs consist of a list of function calls or a <a href="Script_(computer_programming)" class="mw-redirect" title="Script (computer programming)">script</a>. The syntax is <a href="Array_programming" title="Array programming">matrix</a>-based and provides various functions for matrix operations. It supports various <a href="Data_structure" title="Data structure">data structures</a> and allows <a href="Object-oriented_programming" title="Object-oriented programming">object-oriented programming</a>.<a href="#cite_note-28">[26]</a>

Its syntax is very similar to MATLAB, and careful programming of a script will allow it to run on both Octave and MATLAB.<a href="#cite_note-29">[27]</a>

Because Octave is made available under the <a href="GNU_General_Public_License" title="GNU General Public License">GNU General Public License</a>, it may be freely changed, copied and used.<a href="#cite_note-about-10">[8]</a> The program runs on <a href="Microsoft_Windows" title="Microsoft Windows">Microsoft Windows</a> and most <a href="Unix" title="Unix">Unix</a> and <a href="Unix-like" title="Unix-like">Unix-like</a> <a href="Operating_system" title="Operating system">operating systems</a>, including <a href="Linux" title="Linux">Linux</a>, <a href="Android_(operating_system)" title="Android (operating system)">Android</a>, and <a href="MacOS" title="MacOS">macOS</a>.<a href="#cite_note-30">[28]</a><a href="#cite_note-31">[29]</a><a href="#cite_note-32">[30]</a>

<div class="mw-heading mw-heading2"><h2 id="Notable_features">Notable features</h2></div>

<div class="mw-heading mw-heading3"><h3 id="Command_and_variable_name_completion">Command and variable name completion</h3></div>

Typing a TAB character on the command line causes Octave to attempt to complete variable, function, and file names (similar to <a href="Bash_(Unix_shell)" title="Bash (Unix shell)">Bash</a>'s <a href="Tab_completion" class="mw-redirect" title="Tab completion">tab completion</a>).

<div class="mw-heading mw-heading3"><h3 id="Command_history">Command history</h3></div>

When running interactively, Octave saves the commands typed in an internal buffer so that they can be recalled and edited.

<div class="mw-heading mw-heading3"><h3 id="Data_structures">Data structures</h3></div>

Octave includes a limited amount of support for organizing data in structures. In this example, we see a structure <style data-mw-deduplicate="TemplateStyles:r886049734">

Octave's <code>&&</code> and <code>||</code> logical <a href="Operator_(programming)" class="mw-redirect" title="Operator (programming)">operators</a> are evaluated in a <a href="Short-circuit_evaluation" title="Short-circuit evaluation">short-circuit</a> fashion (like the corresponding operators in the <a href="C_(programming_language)" title="C (programming language)">C</a> language), in contrast to the element-by-element operators <code>&</code> and <code>|</code>.

<div role="note" class="hatnote navigation-not-searchable">Main article: <a href="Increment_and_decrement_operators" title="Increment and decrement operators">Increment and decrement operators</a></div>

Octave includes the C-like <a href="Increment_and_decrement_operators" title="Increment and decrement operators">increment and decrement operators</a> <code>++</code> and <code>--</code> in both their prefix and postfix forms.

Octave also does <a href="Augmented_assignment" title="Augmented assignment">augmented assignment</a>, e.g. <code>x += 5</code>.

<div class="mw-heading mw-heading3"><h3 id="Unwind-protect">Unwind-protect</h3></div>

Octave supports a limited form of <a href="Exception_handling" title="Exception handling">exception handling</a> modelled after the <a rel="nofollow" class="external text" href="http://www.lispworks.com/documentation/HyperSpec/Body/s_unwind.htm"><code>unwind_protect</code></a> of <a href="Lisp_(programming_language)" title="Lisp (programming language)">Lisp</a>. The general form of an unwind_protect block looks like this:

<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre>unwind_protect

body

unwind_protect_cleanup

cleanup

end_unwind_protect

</pre></div>

As a general rule, GNU Octave recognizes as termination of a given <code>block</code> either the keyword <code>end</code> (which is compatible with the MATLAB language) or a more specific keyword <code>endblock</code> or, in some cases, <code>end_block</code>. As a consequence, an <code>unwind_protect</code> block can be terminated either with the keyword <code>end_unwind_protect</code> as in the example, or with the more portable keyword <code>end</code>.

The cleanup part of the block is always executed. In case an exception is raised by the body part, cleanup is executed immediately before propagating the exception outside the block <code>unwind_protect</code>.

GNU Octave also supports another form of exception handling (compatible with the MATLAB language):

<div class="mw-highlight mw-highlight-lang-matlab mw-content-ltr" dir="ltr"><pre>try

body

catch

exception_handling

end

</pre></div>

This latter form differs from an <code>unwind_protect</code> block in two ways. First, exception_handling is only executed when an exception is raised by body. Second, after the execution of exception_handling the exception is not propagated outside the block (unless a <code>rethrow( lasterror )</code> statement is explicitly inserted within the exception_handling code).

<div class="mw-heading mw-heading3"><h3 id="Variable-length_argument_lists">Variable-length argument lists</h3></div>

Octave has a mechanism for handling functions that take an unspecified number of arguments without explicit upper limit. To specify a list of zero or more arguments, use the special argument <code>varargin</code> as the last (or only) argument in the list. <code>varargin</code> is a cell array containing all the input arguments.

<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre>function s = plus (varargin)

if (nargin==0)

s = 0;

else

s = varargin{1} + plus (varargin{2:nargin});

end

</pre></div>

<div class="mw-heading mw-heading3"><h3 id="Variable-length_return_lists">Variable-length return lists</h3></div>

A function can be set up to return any number of values by using the special return value <code>varargout</code>. For example:

<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre>function varargout = multiassign (data)

for k=1:nargout

varargout{k} = data(:,k);

end

</pre></div>

<div class="mw-heading mw-heading3"><h3 id="C++_integration">C++ integration</h3></div>

It is also possible to execute Octave code directly in a C++ program. For example, here is a code snippet for calling <code>rand([10,1])</code>:

<div class="mw-highlight mw-highlight-lang-cpp mw-content-ltr" dir="ltr"><pre>#include <octave/oct.h>

...

ColumnVector NumRands(2);

NumRands(0) = 10;

NumRands(1) = 1;

octave_value_list f_arg, f_ret;

f_arg(0) = octave_value(NumRands);

f_ret = feval("rand", f_arg, 1);

Matrix unis(f_ret(0).matrix_value());

</pre></div>

C and C++ code can be integrated into GNU Octave by creating oct files, or using the MATLAB compatible <a href="MEX_file" title="MEX file">MEX files</a>.

<div class="mw-heading mw-heading2"><h2 id="MATLAB_compatibility"> MATLAB compatibility</h2></div>

Octave has been built with MATLAB compatibility in mind, and shares many features with MATLAB:

<ol><li>Matrices as fundamental data type.</li>

<li>Built-in support for complex numbers.</li>

<li>Powerful built-in math functions and extensive function libraries.</li>

<li>Extensibility in the form of user-defined functions.</li></ol>

Octave treats incompatibility with MATLAB as a <a href="Bug_(software)" class="mw-redirect" title="Bug (software)">bug</a>; therefore, it could be considered a <a href="Software_clone" class="mw-redirect" title="Software clone">software clone</a>, which does not infringe <a href="Software_copyright" title="Software copyright">software copyright</a> as per <a href="Lotus_v._Borland" class="mw-redirect" title="Lotus v.

Several 3rd-party graphical front-ends have also been developed, like <a href="Toolbox_(software)" title="Toolbox (software)">ToolboX</a> for coding education.

<div class="mw-heading mw-heading2"><h2 id="GUI_applications">GUI applications</h2></div>

With Octave code, the user can create GUI applications. See <a rel="nofollow" class="external text" href="https://octave.org/doc/v7.1.0/GUI-Development.html">GUI Development (GNU Octave (version 7.1.0))</a>. Below are some examples:

Button, edit control, checkbox<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre># create figure and panel on it

f = figure;

# create a button (default style)

b1 = uicontrol (f, "string", "A Button", "position",[10 10 150 40]);

# create an edit control

e1 = uicontrol (f, "style", "edit", "string", "editable text", "position",[10 60 300 40]);

# create a checkbox

c1 = uicontrol (f, "style", "checkbox", "string", "a checkbox", "position",[10 120 150 40]);

</pre></div>Textbox<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre>prompt = {"Width", "Height", "Depth"};

defaults = {"1.10", "2.20", "3.30"};

rowscols = [1,10; 2,20; 3,30];

dims = inputdlg (prompt, "Enter Box Dimensions", rowscols, defaults);

</pre></div>Listbox with message boxes.<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre>my_options = {"An item", "another", "yet another"};

[sel, ok] = listdlg ("ListString", my_options, "SelectionMode", "Multiple");

if (ok == 1)

msgbox ("You selected:");

for i = 1:numel (sel)

msgbox (sprintf ("\t%s", my_options{sel(i)}));

endfor

else

msgbox ("You cancelled.");

endif

</pre></div>Radiobuttons<div class="mw-highlight mw-highlight-lang-octave mw-content-ltr" dir="ltr"><pre># create figure and panel on it

f = figure;

# create a button group

gp = uibuttongroup (f, "Position", [ 0 0.5 1 1])

# create a buttons in the group

b1 = uicontrol (gp, "style", "radiobutton", "string", "Choice 1", "Position", [ 10 150 100 50 ]);

b2 = uicontrol (gp, "style", "radiobutton", "string", "Choice 2", "Position", [ 10 50 100 30 ]);

# create a button not in the group

b3 = uicontrol (f, "style", "radiobutton","string", "Not in the group","Position", [ 10 50 100 50 ]);

</pre></div>

<div class="mw-heading mw-heading2"><h2 id="Packages">Packages</h2></div>

Octave also has many packages available. Those packages are located at Octave-Forge <a rel="nofollow" class="external text" href="https://octave.sourceforge.io/packages.php">Octave Forge - Packages</a>, or <a rel="nofollow" class="external text" href="https://gnu-octave.github.io/packages/symbolic">GitHub Octave Packages</a>. It is also possible for anyone to create and maintain packages.
