How to combind a 1d Matrix with a 3d Matrix to form a 4d Matrix?

I have a matrix A in the shape 10000x28x28 and a matrix B in the shape 10000x1 and I need them in the shape 28x28x1x10000 (Im trying to achieve this but my starting point is a little diffrent: https://de.mathworks.com/matlabcentral/answers/349616-how-to-train-a-network-with-non-image-data-mnist#answer_275489)

How can I do this?

Thanks in advance

A = rand(10000,28,28);
B = rand(10000,1);

A = permute(A, [2 3 4 1]);
B = permute(B, [4 3 2 1]);
size(A)

ans = 1×4

28 28 1 10000

size(B)

ans = 1×4

1 1 1 10000

C = A.*B;
size(C)

ans = 1×4

28 28 1 10000
