Transform a two dimensional into a three dimensional and combine with another three dimensional array

Hi, I have this matrix

A=randn(4,3);

and I want to transform it in a three dimensional matrix by stacking that matrix 5 times (without using repmat). Then, I want to horizontally combine that matrix with the matrix

B=zeros(4,10,5)

Could you help me? Thanks a lot!

A=randn(4,3)
out=[A(:,:,ones(1,5)) zeros(4,10,5)]

Repmat is an efficient method...

 A = randn(4,3);

 for i = 5:-1:1
  B(:,:,5) = A;
 end

 B(:,end+(1:10),:) = zeros(4,10,5);
