Answer 1

[Matt Fig]

N = 2;  % The number of times each element will repeat...  
h2 = reshape(repmat(h,N,1),1,N*length(h))

[Matt Tearle]

or h2 = repmat(h,N,1); h2 = h2(:);

Just because I love the x(:) trick.

[Matt Tearle]

or h2 = zeros(1,2*length(h)); h2(1:2:end) = h; h2(2:2:end) = h;

[Walter Roberson]

h2 = reshape(repmat(h,N,1),numels(h)*N,1);
