I am trying to find the best polynomial fit for my data set, but LabVIEW occationally outputs the error -20116. What does that represent?
The error -20116 is a generic error that indicates a feasible solution was not found. Hence, in the present case, it means that parameters that were fed to the General Polynomial Fit VI were inappropriate for the given set of data. Try other polynomial order, method, algorithm, etc..
The error -20116 would occur when a right solution is not found for a general mathematical problem. Hence, you may see the same error with other categories of VIs, for example Filter VIs.
