Hi,

I have the data of X and Y as shown in the image

I wrote the for loop as shown here, it is making the calculations for the first column. But, how to make the calculations for the rest of the columns in the same for loop?

for i=1:3
    y=[Y1{i,1}']
    x=[X{i,1}']
              A= fminsearch(@(par_fit) funccoats(par_fit,x,y),rand(1,2));
              B(i,1)=A(:,1)
              C(i,1)=A(:,2)
   end

Thanks

Maybe just add another loop over the columns. E.g.,

for c=1:4
    for i=1:3
        y=[Y1{i,c}']
        x=[X{i,c}']
        A= fminsearch(@(par_fit) funccoats(par_fit,x,y),rand(1,2));
        B(i,c)=A(:,1)
        C(i,c)=A(:,2)
    end
end
