Array division of two non-zero arrays returns zero

3 views (last 30 days)
Hi everyone!
I have 2 very long arrays X and Y (each with dimensions 16384x1) with the first one with values in the range 0.230286000000000-0.189370000000000 and the second one with range 12.191100000000000-0.041792500000000.
I need to perform array divison Y/X so to get a matrix of 16384x16384. However, when I perform the division all the entries are zero. This is the format I'm using:
format long
W = double(Y)/double(X);
Any hints on where the problem may be?
Thank you!

W = double(Y(:))./double(X(:).');
