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.

在 MATLAB Online 中打开

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.
