cdn_baumert {HadamardR} | R Documentation |
Checks Hadamard Matrix can be constructed using Baumert-Hall arrays of order 12.
cdn_baumert(order)
order |
integer, order of Hadamard matrix to be checked. |
Baumert-Hall array is a generalization of Williamson Array. In case, Williamson matrices are available for order/12, the method return 6 otherwise it returns NULL.
The availabile Williamson sequences in the internal data sets is seq(1,63, 2) except 15, 35, 47, 53, 59 in the internal table.
