Origin Version (Select Help-->About Origin): 7.0
Operating System: window xp

I have a question about mutliexponential decay fitting, I want to do a 4-exponential decay fitting, how to make a fitting function like this y=y0+A1*exp(-(x-xc)/t1)+A2*exp(-(x-xc)/t2)+A3*exp(-(x-xc)/t3)+A4*exp(-(x-xc)/t4), how to make the fitting faster.

Thanks a lot
