Gamma Variate Curve Fitting [message #35516]

I have been trying for a week now to fit data to a gamma variate curve
using the curve fitting algorithms built into IDL. Every time I use
CurveFit it tells me my data does not converge and every time I use
SVDFIT my program crashes and exits out of IDL automatically! I made
sure that my inital guesses were VERY close to the actual test data I
am using and I'm still stuck. Does anyone have any experience fitting
this type of non-linear curve using IDL? If I was using anything else
I would probably use the simplex method but there doesnt' seem to be a
downhill simplex curve fitting algorithm in IDL. HELP!!!
