Origin Version (Select Help-->About Origin): 7.5 SR4
Operating System: Windows XP
Several weeks ago, I asked a question about the fitting with summation and single integral. At that time, I received some replies from Mike Buess. Then, I solved the problem (Thank Mike).
You can find the story here.

But, I need your help again, because the fitting function became more complex. I tried to modify Mike's code, but I failed.
My fitting function includes the summation and single and double integral.
F(x)=exp(-P1*x)*sum(n=0 to k){F(n,P2,P3,x)+G(P4,x)*integral[integral[H(n,P1,...,P4,x1,s),s=0 to x1], x1=0 to x]}
+ P1*P2*exp(-P1*x)*sum(n=0 to k){integral[Q(n,P1...P4,s), s=0 to x]}.
If you have a good idea, please let me know.
Thanks,
Kang-Bin.

Revisited: fitting with sum and double integral
