Getting coefficients from a for loop

I want to run the code below inside a for loop so that I can run through ten versions of a, i.e. a(:,:,1) to a(:,:,10).
Each of these will produce a column vector from which I want to fit an exponential decay to and then remove the coefficients from so I have a vector with ten coefficient in. Can anyone show me a easy way of doing this??
for t=1:10;
image=a(:,:,t);
image=im2double(image);
Isum=sum(image,1);
[Imax,Iloc]=max(Isum);
I=image(:,Iloc);
plot(I);
fit=fit(L,I,'exp1')
end

exponential fit outputs two coefficients each time, not one -- a * exp(b). Which of the two did you want to store?

Thank you for your reply, I am looking for the b coefficient.
