Hi,
I have a rank-5 tensor A and a rank-2 matrix B, and I want to captured the first two dimentions of A as slices and do the mutiplication with B to form an output C.
I can do it as below by using 3 for loops. But that is not efficient. How can I do it vectorizedly (i.e. without using the for loops)?
Many thanks!
My current code
A=randn(3,4,8,2,14);B=randn(7,3);C=zeros(7,4,8,2,14); % (7, 4) is due to matrix mutiplication of (7, 3)x(3, 4)
for i=1:8 for j=1:2 for k=1:14 A_slice=A(:,:,i,j,k); C_slice=B*A_slice; C(:,:,i,j,k)=C_slice; end endend C % the output I want
