Make that
a = rand(10);
b = a(1:2:rows(a),:);
c = b(vec(repmat(1:rows(b),2,1)),:)
and similarly for columns
a = rand(10);
b = a(:,1:2:columns(a));
c = b(:,vec(repmat(1:columns(b),2,1)),:)

Hi,
Is there a vectorized way to delete every other row/column in a matrix?
Similarly to duplicate every other row/column?
Thanks
Marius
Something like that?
a = rand(10);
b = a(1:2:rows(a), :)
