Fitting multiple dependent and independent variables

I'm trying to fit data of the form [u; v] = [Gux Guy; Gvx Gvy]*[x; y]. I know the values of my independent variables x & y, as well as the values of the dependent variables u & v. I'll typically have 8 sets of data with one value each for u, v, x, and y. I want to find the values of the G matrix elements that give the closest match of u & v to the 8 values I have for each of them. the default fit function only works for a single dependent variable, unfortunately. Is there another function that will accept two dependent variables (and two independent variables) for fitting?

Yes, you can use the mvregress command.

The syntax is a bit tricky. Be sure to read the documentation carefully. Also, my answer here gives another example.
