Hi,
I have a set of data for a function of two variables f(x1,x2). My function is exponential for x1 with two coefficients that depend on x2:
f(x1,x2)=a*(x1)^b, where a and b are functions of x2.
I found a and b for several values of x2, so I do have equations f(x1) for some fixed x2. I am now trying to find a general equation f(x1,x2).
Is there a way to do curve fitting with two variables-- Mathcad help shows only how to curve fit with one variable?
Every input is appreciated.
If you have Mathcad 15 or Prime, then you could try the multivariate fitting function multidfit. Otherwise, a solve block will probably handle your problem.
Stuart and Richard,
Thanks for your replies. I'll try to digest your suggestions.
