lucast005	Posted - 05/30/2014 : 07:05:43 AM Origin Ver. and Service Release (Select Help-->About Origin): Origin 9.1.0 (64-bit) Sr2 Operating System: Windows 7 Enterprise SP1 64bits My doubt is about the following calculation: I have defined an equation as Origin C Function Type. The Non Linear Curve Fit works perfect, and know i want to make the fit but with calculations. I mean: I have several parameteres but i want to pay attention on 3 (the rest are going to be fixed): cmc, r and K. I want to know if its possible to make a routine where i can fixed one, set another as x-variable and check how the third parameter changes. Its like a simmulation but with a fit data. Thank you very much for your attention and waiting for your answer Best regards lucast005
