not in general. The plotting functions of pst-plot and pst-3dplot
can do both, computations and displaying the result of a
2d/3d function. The important difference is, that the
algorithm or at least the math function has to be in UPN
(postfix) notation. For functions there exists a infixplot
package which converts an algebraic notation of a function
into the stack orientated PostScript notation.
