Two-level full-factorial designs.

Syntax

X = ff2n(n)

Description

X = ff2n(n) creates a two-level full-factorial design, X. n is the number of columns of X. The number of rows is 2ⁿ.

Example

X = ff2n(3)

X =

     0     0     0
     0     0     1
     0     1     0
     0     1     1
     1     0     0
     1     0     1
     1     1     0
     1     1     1

X is the binary representation of the numbers from 0 to 2ⁿ-1.
