Abstract :
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.
