A question concerning contour plots. Does IDL have a call to easily plot
the zero level curves of an arbitrary function, i.e. given f(x,y)=C with
C some constant, plot g(x,y)=0 where g(x,y)=f(x,y)-C.
Example: Can I plot the zeros of function g(x,y) = x^2 +y^2 - 4. If so,
can I create a similar plot of a surface g(x,y,z)?
Such functionality is fairly trivial in Mathematica and MATLAB.
As always,
Ed Wright
