ff2n (Statistics Toolbox)

Two-level full-factorial designs

Syntax

```
X = ff2n(n)
```

Description

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