How to do curve fitting with two variables (using lsqcurvefit )

Hi

I'm using Matlab 7

I tried lsqcurvefit function to find params when it was with one variable, like y=f(x) How can I do the same when I have 2 inputs like z=f(x,y)?

Thank you for your help, Janna

What you need is the Surface fitting tool.
