Follow-up Comment #1:

Thank you for the bug report.  According to bug #55742, Octave only supported
this undocumented Matlab feature of extra arguments  for a short time in
Octave 4.4.0.  Ultimately, it was decided in bug #46807 not to support this
undocumented feature, as it can be silently removed at any time in Matlab.

But no worries.  There is a much more consistent way of getting your job done
using anonymous functions.  You can find an example in the Matlab manual,
section "Minimize with Extra Parameters"

https://www.mathworks.com/help/matlab/ref/fminsearch.html

or if you post your function here, we can easily suggest an appropriate
anonymous functions declaration.

As you are on MS Windows, maybe you decide to upgrade to Octave 5.1.0?

I close this bug report as duplicate, but you can post your example function
"fssr" here with some idea of the parameters y,x,ymax,xmax to obtain further
guidance.
