Is it possible to use the fit() function to fit a model with 3 independent variables and many parameters (coefficients)? Reading through the documentation, I get the impression that Matlab only supports 2 independent variables. Any insight would be helpful.
Thanks, Justin

For more general kinds of fitting, you probably need Optimization Toolbox solvers.

Do you have the Statistics or Optimization Toolboxes? If so:
Optim:
* doc lsqcurvefit
* doc lsqlin
* doc lsqnonlin
Stats:
* doc NonlinearModel
* doc LinearModel
* doc regress
I'm missing many others, we can point you in a more specific direction if you have more details.
