Hi, as mentioned in the title i am looking for a way to achieve a particular element wise multiplication. For example given:
A = [ 1 2 3]; B = [1 2 3;4 5 6;7 8 9];
is it possible to achieve as a result something like this:
result = cat(1,A(1).*B,A(2).*B,A(3).*B)
but with unkown A array length and without any loops ?
Thank you in advance.
