Hello:In the Constrained Nonlinear Curve Fit VI, the Help for the VI states that if the number of iterations exceeds max iterations specified in the termination control, the fitting process terminates. Would this not indicate that if the above condition is met, the number of iterations recorded (an output of this VI) should be equal to the max iterations specified (since the VI is exits at this point). I believe I have seen situations where this condition is met, yet the number of iterations recorded is greater than the max iterations I have specified in the termination control. Has anyone else seen this?Thanks,Don

Also, I include weights directly within my models as parameters (for my mixed guassian-Laurentzian model), so I don't end up using the input 'Weight,' and this approach seems to be working pretty well right now.
