How to fit a function with two or more dependant variables (outputs)?

8 views (last 30 days)
I have a complex matlab function that takes x -> (y1,y2) based on several passed parameters. I would like to use curve fitting to find the optimal parameters that fit the function to data. Are there any such tools in MATLAB to accomplish this? nlinfit and the others seem to only want to work with a single independant variable column vector and a single dependant variable column vector (i.e. x -> y).

What is the difference between an array and a vector ?
If you enter X and Y as independent and dependent vectors, all should work out fine.

lsqcurvefit does not care about the dimensionality of the independent or dependant variables.
