I'd like to draw a monkey saddle surface using matlab. But how do I plot a function of several variables in matlab? I never did that before. I can define $x$ and $y$ as two vectors and then according to wikipedia the monkey saddle equation is $x^3-3xy^2$ so all I wanna do is plot that function? Are there any more monkey saddle surfaces that might be nicer than this one?
The easiest way is to use the
should work. I don't have my MATLAB install on this computer, so I cannot verify.
