Adding rows to a matrix after every even row

Is there a way, without using a for loop, to add a row of nan's to a matrix after every even row of the original matrix? For example,
A = [6;2;2;1;1;0;]; %original A matrix will always have an even number of elements
becomes
A = [6;2;NaN;2;1;NaN;1;0];
My initial plane was to make a vector of NaN's having the same size as the final matrix.
temp = nan(size(A,1)/2 - 1,:);

A = [6;2;2;1;1;0]
B=[reshape(A,2,[]);nan(1,numel(A)/2)];
B=B(:)
