Editing GNU Octave (section)

===C++ integration===
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>:
<syntaxhighlight lang="cpp">
#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());
</syntaxhighlight>

C and C++ code can be integrated into GNU Octave by creating oct files, or using the MATLAB compatible [[MEX file]]s.
