# MATLAB: Make a variable

variables

I have to make a variable which has the sign %s as many times as the variable x is.
This means if x = 15 then i need to make
B = [%s %s %s %s %s %s %s %s %s %s %s %s %s %s %s]
While also keep the spaces between them. So I can paste it into textscan.
Is there a way to produce B. I could make B as 2 columns one for % and one for s but when I transpose it the result is completely wrong.
%%%%%%%%%%%%%% ssssssssssssss
Any ideas? Thank you very much

B = repmat('%s ', 1, x);
