Two-level full factorial design
dFF2 = ff2n(n)
dFF2 = ff2n(n) gives factor settings dFF2 for a two-level full factorial design with n factors. dFF2 is m-by-n, where m is the number of treatments in the full-factorial design. Each row of dFF2 corresponds to a single treatment. Each column contains the settings for a single factor, with values of 0 and 1 for the two levels.
