MATLAB: Create a matrix (24,72) using ‘for’ loop.

Question

How can I use the loop 'for' or other, to produce the same matrix (24,72) depicted in the figure? kind regards.

Answer 1

since it is a nice simple pattern of (zeros for columns that are a multiple of 3) then:

 DesiredResult = ones(24,72);
 DesiredResult(:,3:3:end)=0;
