In HadamardR: Hadamard Matrix Generation

Description

Checks Hadamard Matrix can be constructed using Baumert-Hall arrays of order 12.

Usage

order

integer, order of Hadamard matrix to be checked.

Details

The availabile Williamson sequences in the internal data sets is seq(1,63, 2) except 15, 35, 47, 53, 59 in the internal table.

Value

6 or NULL
