Hello people:

I have the following code:

L=500;         
S=ones(1,L);
n=50;
S((L/2-n(i)/2):(L/2+n(i)/2))=0;

I would like to have a matrix M(10,L) where M(1,L) is S when n=50, M(2,L) is S when n=100 and M(3,L) is n=150 and so on...

Does anyone knows how to do it using a loop?

Thank you,

Maria

With only three iterations, the easiest way is to use a for loop:

L=500;         
S=ones(1,L);
M = zeros(10,L);
n = [50, 100, 150];
for i = 1:length(n)
    S((L/2-n(i)/2):(L/2+n(i)/2))=0;
    M(i,:) = S;
end

EDIT — Inserted ‘M’ preallocation.
