MATLAB: Tensor product 2 matrices – kronecker product

Question

A question regarding the tensor product of 2 matrices, in combination with the Kronecker product.

I have 2 matrices: Qz and Qx.

Qx is Ns* Nx;

Qz is Ns * Nz.

Ns is the total states, consisting of all possible combinations of x and z (so Ns = Nx * Nz).

Lets say Ns = 14400; Nx = 3600; Nz = 4.

Then, I would like to multiply them using Tensor products, i.e. Q = Qz * Qx.

Is there any way to do this and to avoid to have a loop and apply the kron-function Ns times, to fill the matrix?

Answer 1

Q=reshape(Qz,Ns,1,[]).*Qx;
Q=Q(:,:);
