Hello,

I believe that I am in a predicament. I have already read that trying to create variables from a loop (using eval like A1, A2, … ) is not advisable and its better to initialize empty matrices using zeros. But I think that I have to breach this. Please advise on alternative options if you know any.

Here's the trouble.

So I need to be creating a cyclic matrix. I will create a base matrix where each element is an identity matrix shifted right by that element. For example I have created a base matrix –

`Ha = 1 2 4 8 16 5 10 20 9 18 25 19 7 14 28`

Now each element is actually supposed to be an identity matrix. All identity matrices's size are 31×31.

So Ha(1,1) is identity matrix of size 31×31 (hereafter referred as eye(31))

Ha (1,2) is eye(31) cyclically shifted right by 2

Ha (1,3) is eye(31) cyclically shifted right by 4

Ha (2,3) is eye(31) cyclically shifted right by 20

And so on…..

I believe that I must be creating variables like A1, A2, A4,…. to as many as I have in Ha.

How do I bypass this without creating variables using loops.

If it helps, the final matrix size is row*31 by col*31 = 3*31, 5*31

Size of Final Matrix = 93, 155
