Dear all, Here I have one question and need you help. When I fit the experimental data, I found the nomal least-squares fit is not good enough, so that I want to add one more constraint on it, which means I need two fitting functions to find the best fitting result at the same time. But from the handbook of Mathematica, one can not find this kind of examples. Everybody only talks about the use of your own (but single) function to fit. So, do anybody know how to solve this problem? (simply speaking: using two fitting constraints in one FindFit) Thank you very much for your help.
