Is it possible to fit data to more than two independent variables using Curve Fitting Toolbox 2.0 (R2009a)?

Problem Description:

I would like to use Curve Fitting Toolbox to fit my data to more than two independent variables.

Solution:

The ability to fit data to more than two independent variables is not available in Curve Fitting Toolbox.

To work around this issue, you can generate your own objective function and use functions from Optimization Toolbox to fit your data to more than two variables.
