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

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

specificallywhat you mean by "interleave".## mary

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