Constrained Fitting [message #19454]

I've been testing a number of the curve fitting routines in IDL with my
data. I've been using mainly CURVEFIT and LMFIT. I have three
parameters in a bi-exponential fit and I need to put constraints on
these parameters. As far as I can tell, putting constraints on the
parameters is not possible with the current fitting routines. Am I
missing something? Is there a different fitting routine that I haven't
found that allows either non-linear least squares fitting or something
like it with constrained fitting parameters?

Thanks for your help.
