<p>Octave and <small>MATLAB</small> are very similar, but handle Java slightly different.
Therefore it may be necessary to detect the environment and use the appropriate
functions. The following function can be used to detect the environment. Due
to the persistent variable it can be called repeatedly without a heavy
performance hit.
</p>
<p>Example:
</p>
<div class="example">
<pre class="example">%%
%% Return: true if the environment is Octave.
%%
function retval = isOctave
persistent cacheval; % speeds up repeated calls
if isempty (cacheval)
cacheval = (exist ("OCTAVE_VERSION", "builtin") > 0);
end
retval = cacheval;
end
</pre></div>
