Hello community !
I need help for a simple problem:
I have a matrix A of Dimension (840,64,1536) and a matrix B of dimension (1536,1)
I need to divide each set A(840,64, i ) by the i-th value of B B(i).
I could do a clumpsy for loop, but would like a smarter approach.
Thanky you for your support!
Florian.
