I suggest you give more detail and/or a small example of what you mean. I, for one, don't understand specifically what you mean by "interleave".

interleaver: it rearrange or reshape the matrix deinterleaver : it restores the original arrangement of the maatrix

Not sure what you mean, but here's one way/interpretation:

m1 = magic(6)
m2 = ones(10, 6)
columns = size(m1, 2)
m1Rows = size(m1, 1)
m2Rows = size(m2, 1)
m3 = zeros(m1Rows+m2Rows, columns);
% Interleave.  If there's any difference in the number of rows,
% the mismatching rows will be zero.
% You could handle that differently if you want to,
% for example, just append the remaining rows
% of the taller array.
for row = 1 : max([m1Rows, m2Rows])
	m3Row = 2 * (row-1)+1;
	if row <= m1Rows
		m3(m3Row, :) = m1(row, :);
	end
	if row <= m2Rows
		m3(m3Row+1, :) = m2(row, :);
	end
end
m3
