Hallo community,
I want to perform two independent nonlinear asymptotic fits with:
(1) y(x) = A(x->infinity) + B*x^(-3) (2) y(x) = A(x->infinity) + B*exp(-x+1) + C*exp(-x+1)^2
I've tried to implement those fits to origin, but it doesn't work, because I have huge problems to write the correct Origin C code. Can you help me?
Thanks, Jan |

What does your A(x->INFINITY) mean? Anyway, you can build a user-define fitting function with 2 dependent variables (y1 & y2) so that they will be fitted simultaneously. http://www.originlab.com/doc/Tutorials/UserDef-FitFunc http://www.originlab.com/doc/Origin-Help/UserDef-FitFunc
