Graphing not working Using Genfit Coefficients

Hello there,

I am using genfit to come with the coefficients for a best fit equation for points I have created. However, when I try to plot the graph using the coefficients to see how accurate is the equation as compared to the points in the same mathcad sheet it won't plot. Can someone help me out. I have attached the mathcad sheet. Thanks.

Hello, Ranjan,

Have you defined your variable (x) ?

Cordially.

Tried defining the variable x but still no luck.

You have defined ORIGIN=1 but you try to use 0 as the first element in the cg1 vector.

Wouldn't a simple power function make a much better fit?

I cannot use a power law as I require the curve fit I am using to input the coefficients into a finite element analysis program.
