a matrix factorization is presented for a Hadamard matrix of order twelve that permits a Hadamard transform of this order to be computed with substantially fewer operations than by simple matrix multiplication. The matrix factorization is extended to Hadamard matrices of order 2nX 12 where n is an integer.
Algorithm, data reduction, Hadamard matrix, Hadamard transform, matrix factorization.
