1970 Computation of the Hadamard Transform and the R- Transform in Ordered Form
abstract
This correspondence describes a method of computing the Hadamard transform and the R-transform. This method produces the transform components in the order of the increasing sequency of the Walsh functions represented by the rows of a symmetric Hadamard matrix for which the sequency of each row is larger than the sequency of the preceding row.
