Hi all
Just a quick question, and will appreciate your help.
Suppose I have w=[a b c d e f] I want a new matrix that gives the product of every two consecutive elements. ie [axb, cxd, exf] and will be a 1x3 matrix
Another factor is the size of w is (mxN), and in the above case, m=2;N=3
So, I also assume length(w)/N might need to be used as well.
Looking for suggestions ASAP
cheers
