I have two quite large matrices with the following sizes:
A = rand(94037,2240) B=rand(2240,2240)
I would like to mutiply each column of A by the transpose of each column of B (bascially two vector multiplication). Therefore each mutiplcation gives me a 2D matrix wih size (94037,2240) and I would like to store the result of each multiplication in a 3d MATRIX.
The thing is I can do this with for-loop as show below but its very slow and in the middle of operation matlab exist, because its quite heavy.
S = zeros(94037,2240,2240);
Is there anyway I can do this without using for loop to speed up the process ?
Thanks for the help.
