stepping through the code, the error occurs at the line:


where M(x) is defined as a symbolic function. It appears that at least currently, fplot in Octave cannot handle a symbolic function. (i did try with a simple polynomial function to verify it wasn't something unique to the function you used.)  I can't confirm whether or not this is a regression from a previous version of symbolic, but did confirm that Matlab 2019a is able to execute the same fplot command without issue.
