Workspace Method jacobianFromYbatch
Description
Sets jacobian based on perturbation calcuations. This function assumes that ybatch contains spectra calculated with some variable perturbed, in comparison to the calculation behind y. The function takes the differences between ybatch and y to form a numerical derived estimate of jacobian. Column i of jacobian equals: (ybatch[i]-y)/pert_size.
