I'm using the lsqfit instruction to fit experimental data to a model consisting of a sum of exponential terms, so the thing is that with some of these models (for example, with a sum of two or five exponentials so far), LabVIEW throws the following error:
Error -23026 occurred at maximum iterations exceeded
Analysis: (Hex 0xFFFFA60E) No optimum found.
I understand that the maximum number of iterations must be increased, so... How can I achieve this? Is there an instruction that modifies the maximum number of iterations related to lsqfit? Is there another way to perform the nonlinear fit besides lsqfit?
