Obtaining the chi square value from a multigaussian fit

I am using the Matlab fit function to fit data with several gaussian functions. It seems to work, I obtain the gaussian parameters but I cannot find the way to get also the chi square of the fit. Should I calculate but myself? No way to have it in the output? Thanks for any suggestion Renzo

Provided you have the right toolbox:

Otherwise, use the residuals of your fit and do the test yourself.
