E.g., assuming N is divisible by 4:
result = repmat(column_vector,N/4,1);
If you have to cover cases where N is not divisible by 4, e.g.,
result = repmat(column_vector,ceil(N/4),1);
result = result(1:N);
or another way
result = column_vector(mod(0:N-1,4)+1);
If your column_vector is not really 4 elements but something else, simply replace 4 with numel(column_vector) in the above code.
