Subject: Re: get fit coefficients from fitting result
Does anyone know how can I save a set of coefficients for different values of k for example.
I have k=0.00475 and do the fitting,using coeffvalues I get 'g' as a 1 by 2 matrix 0.002 0.63,
then I want to have it for k ranging from 0 to 0.008 with step size 0.001;
I put it in a loop but it did not work!
