The fact that you reached line 202 presumably means you are in an Octave environment, not a MATLAB environment. (I'm guessing that that code is using this ismatlab function.)
That's not a MATLAB error, and is presumably an Octave error. The error message you are getting suggests that there is no longer an Octave warning labeled "Octave:abbreviated-property-match".
Perhaps do an internet search on that string?
