Subject: Re: get fit coefficients from fitting result
Hello,

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!

K=0.0:0.001:0.0008;

for iK=1:length(KK),

K=KK(iK)

modelNEURON_excitatory;

name=strcat('g_modelNEURON_excitatory_K',num2str(K),'.mat');

save(name,'g','-mat');

end

Thanks,
