title: Is there an Octave equivalent of Matlab's `contains` function?
body: <p>Is there an equivalent of MATLAB's <a href="https://www.mathworks.com/help/matlab/ref/contains.html" rel="nofollow noreferrer"><code>contains</code></a> function in Octave? Or, is there a simpler solution than writing my own function in Octave to replicate this functionality? I am in the process of switching to Octave from MATLAB and I use <code>contains</code> throughout my MATLAB scripts.</p>
