Function File: [fx, fy, fz] = feval (function_name, x, y, z)

Evaluate a function at a specific point of the domain and return the value. The input parameters are the function and the coordinates of the point where it has to be evaluated.

Be aware that the number of input arguments and outputs depends on the dimensions of its domain and codomain.

value = feval (p, x , y)

This is the expected call for a scalar field on a bidimensional domain.
