Hi,
I have a column vector with 65536 integer data, and out of this vector I want to create a matrix with 32 columns x 2048 rows where each column is a downsampling by 32 of the original vector,, with a phase shift for the starting point going from 0 to 15.
Is there a way to do this without using a loop ?
Thanks,
Stéphane.

I found the solution by looking at Matlab blogs and discussions:
reshape(initial 65536 data vector, 32, 2048) is doing the job I needed as in each line I have now datas 1, 33, 65, ..., then 2, 34, 66, ...
