Matrix expansion performance [message #43274]

Hi,
I have a matrix A (m,n) is and I want to create a matrix B(m,n,p) such that
each B(*,*,i) slice equals A. p is very large and n is usually smaller than
m so I have:

B=bytArr(m,n,p)
C=byteArr(p) + 1
FOR i = 0, n-1 DO B[*,i,*] = REFORM(A[*,i]) # p

Quite fast, but not enough for my needs. Any one has better sugestions?

Still stuck in IDL 5.4, by the way.

Thanks,
Ricardo
