Hi.
I have written an algorithm that computes an array "b" for each ith iteration [i={1,2,3,4}], and I would like to save those arrays in a structure called "A".
How to save those arrays in the structure "A" where its elements are function of "i", i.e, A = {b1, b2,b3, b4} and to get b1 for instance, one would have to type A.b1.
Regards.

Note that using a non-scalar structure would be more efficient than generating fieldnames.

Indexing is much faster and less buggy than messing around forcing meta-data (i.e. that index) into some fieldnames.

Thanks Madhan for your input, but I would like to get is, at each iteration "i", the array should be saved directly and named after the index "i".
Ex: i=1 => b (n x n) is computed then savedin the strcture A as A.b1.
i=2 => b (n x n) is computed then savedin the strcture A as A.b2
You now what I mean now?

A=struct; % an example
for k=1:5
A.(sprintf('b%d',k))=rand(5);
end

Thanks a lot Madhan.
That's exactly what I was looking for.
