Hello. I am using curvefit in IDL 4.0.1 for fitting a set of data point
with a curve of the form
y=a*(exp((x-b)/c)-1)
where x is the dependent variable and a,b,c are the fit parameters.
It usually works fine, but sometimes, when the data are really bad, it
goes into an infinite loop. Since the fit is embedded into a more
complex program, this is very annoying. I would rather like the routine
to exit nicely, even without performing the fit. Has anyone found the
same problem? Is there a solution? Thanks a lot.
Emilio
