octave: How to Distinguish Between Octave and Matlab

 
 D.4 How to Distinguish Between Octave and Matlab
 ================================================
 
 Octave and MATLAB 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.
 
    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
