Shifting elements and replacing empty places with zeros

How to convert matrix A =[3 ,7, 9, 2] to matrix B = [3, 7, 9, 2; 0, 3, 9, 2; 0, 0, 3, 9; 0, 0, 0, 3] using matlab

The B that you have provided is not what the title of your post describes. I assume you meant the following,

A =[3 ,7, 9, 2];

B=toeplitz([A(1),zeros(1,numel(A)-1)],A)

B = 4×4

3 7 9 2 0 3 7 9 0 0 3 7 0 0 0 3

Thank you

@Matt J - Can we do this without using toeplitz function?

[Matt J]

Of course!

[Ritu Giri]

Can you please on that?

[Matt J]

No, because that would probably be a homework problem.
