fittype in a loop

Hello to everyone,

I have the following code:

Math_model2 = fittype('f*exp(D_star*-b_all) + (1-f)*exp(5e-4*-b_all)','dependent',{'y_all_bValues'},'independent',{'b_all'},'coefficients', {'f','D_star'});

If I run this code it works without problem.

The problem that I have is that I want the 5e-4 in the code to be a variable. So I could use for example the Variable 'D' so I can use Math_model2 in a loop with different D's like this:

for D=x:n

Math_model2 = fittype('f*exp(D_star*-b_all) + (1-f)*exp(D*-b_all)','dependent',{'y_all_bValues'},'independent',{'b_all'},'coefficients', {'f','D_star'});

end

Can someone please help me out with this?

I have this feeling that it has a very simple soulution.

Thanks in advance

This shows an example of how to use 'D' in the expression.

for D=1:10
    expr = sprintf('f*exp(D_star*-b_all) + (1-f)*exp(%f*-b_all)', D);
    ath_model2 = fittype(expr,'dependent',{'y_all_bValues'},'independent',{'b_all'},'coefficients', {'f','D_star'});
end
