Parameter search limits for fitnlm

Is there a way to constrain the search for parameter values on fitnlm? I keep running into issues when trying to solve for 3 to 9 variables and on a single iteration one of the parameters takes a value that causes an error and the whole thing stops. Then I have to do a bunch of exploratory analysis to come up with a better starting value.

Thanks, Joe

It is not possible to constrain the parameters in the Statistics Toolbox functions. The Optimization Toolbox function lsqcurvefit will allow you to limit the to ranges.
