8.5 Discrete Hadamard Transform

Image transforms.

The functions DiscreteHadamardTransform, InverseDiscreteHadamardTransform, and HadamardMatrix take an option that changes the ordering of the rows and columns of the matrix.

Option for HadamardMatrix, InverseHadamardMatrix, and DiscreteHadamardTransform.

The ith bit of a binary representation of an integer may be obtained using IntegerDigits. The sum defines an inner product of two vectors of length m, whose elements are the binary digits of the m-bit binary representations of the integers n and k.
