Thanks!  I added it to this "nice to have" list:

Probably this is a fairly straightforward fix: if anyone wants to tackle this, look at `@sym/ezplot` and friends for example.

The Matlab function fplot works with symbolic functions as well.
For example, this code

syms x
f(x)=x^2;
fplot(f(x))

plots the parabola on the dafault [-5,5] interval.

symbolic 2.8.0 on GNu Octave 5.1.1 produces

error: isalnum: not defined for class
error: called from
    fplot at line 100 column 3
