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;

You could do this with a loop:
A = ones(24,72);
for k = 1:72
if rem(k,3) == 0
A(:,k) = 0;
end
end
or you could do this in one line:
A = repmat([1 1 0],24,72/3);
The latter is much faster and more elegant.
