Your question is not clear. If you delete odd and even rows at the same time, then you're left with nothing.

This is very basic matrix indexing. To delete odd rows:
m(1:2:end, :) = []
To delete even columns:
m(:, 2:2:end) = []
Note that you can't do both at once. If you want to delete both odd rows and columns, you have to do it in two steps:
m(1:2:end, :) = []; %delete odd rows
m(:, 1:2:end) = []; %delete odd columns
