I can use the constraint tab and put my constraints there. If I have 2-3 constraints there, it works fine. Anymore and fitting is not converging with reasons unknown. Can you please tell me is there is any limit to number of linear constraints I can put in origin for a fitting function? I do not see any such limit anywhere in the documentations. I am using Origin 8.5.1 on windows 7. AB [/quote]   Check here to include your profile signature. Check here to subscribe to this topic.
