Use vector to create 3rd dimension at each point in a matrix

I have an N-by-N matrix and a vector of length M. I want to create a 3-D array where at each point in the matrix, the third dimension is my vector.

This is the code I have, but I would like to know if there is a faster way that I can do this (probably without a loop). Any ideas?

N=10;
vec=1:5;
for i=1:N
    for j=1:N
        array(:,i,j)=vec;
    end
end

N = 10 ;
vec = 1:5 ; 
b = repmat(vec',1,N,N) ;
