Hello,

I don't use the symbolic package often and if I'm doing something wrong I
apologize. I found that my symbolic code from 2020 no longer works, and even a
basic "syms x" statement gives a SymPy error. I have verified that my SymPy
installation is proper. Is this a bug or is it user error?


octave:10> pkg load symbolic
octave:11> syms x

    Try "sympref reset" and repeat your command?
