Details:

This originally came up trying to solve a system of non-linear equations using
the symbolic package.  Some routine in vpasolve tried to use polar
coordinates.  To reproduce the problem

pkg install -forge symbolic
pkg load symbolic
syms x
ezplot(erf(x), [-pi, pi])+ezplot(exp_polar(x),[-1,1])

The erf function  plots, the exp_polar function throws this error
error: 'exp_polar' undefined near line 1 column 32

As I understand both functions are part of the symbolic package.
