Hi,
I'm trying to fit real data with the Levenburg-Marquardt (L-M) VI to extract some material parameters from a model equation. I'm using the 'function is VI' instance of the L-M VI, where I think I've got my model equation VI referenced and typed correctly. However, the L-M fitting VI returns my initial guess parameters as the optimized output, regardless of initial parameter choice. Is my data set too small, or is there some obvious wiring problems here, or.....?
Any help is greatly appreciated. I'm using LV 2013. (This is my first shot at data consumption; usually I just need LV for equipment automation, which is cake compared...) :)
