Origin Version (Select Help-->About Origin): OriginPro 8
Operating System:
I want to evaluate the parameters of a set of curves. Each curve depends on three parameter (P1,P2 and P3) whereas the parameters P1 and P2 are const for all curves (i.e. they are coupled) and P3 varies from curve to curve. The data are organized as follows:
Col(x) col(y1) col(y2) col(3) ... col(y8)
The function of the curves reads as:
y = sqrt((P1/(1+(x*P1*P3)^2)+P2)^2 + (P1^2*x*P3/(1+(x*P1*P3)^2))^2)
How can I manage this?
Any help is appreciated
