Matrix Multiplication with its transpose in the loop

Hi,
Let's say I have a matrix
A = [1 2 3 4 5
2 3 4 5 6
3 4 5 6 7
4 5 6 7 8]
I need to do matrix multiplication i.e. A'*A, but not all the rows and the column at once. For example, I want to multiply the first two column of the matrix first and obtain a result (let's say r1), then column 1, 2 and 3 multiplied with its transpose, obtain the result (let's say r2) and then column 1,2,3, and 4 multiplied with its transpose and the result is r3 and so on. I have to save the result in the matrix, let's say B
B = [r1 0 0 0
r1 r2 0 0
r1 r2 r3 0
.....]
Can anyone help me with this?
Thank you!
