DiscreteHadamardTransform
DiscreteHadamardTransform[list]
gives the discrete Hadamard transform of list.
Details and Options
- The discrete Hadamard transform
of a list 
of length 
is by default defined to be 
, where 
, 
is the 
bit in the binary representation of the integer 
, and 
. - DiscreteHadamardTransform returns a list that has a power of 2 length. If the length of the input list is not a power of 2, it is zero padded to a length that is the smallest power of 2 greater than
. - DiscreteHadamardTransform takes an option
. Sequency is the number of zero crossings of the Hadamard basis sequences. The default is "SequencyOrdered"->True, where the sequency increases with row or column index. With "SequencyOrdered"->False, 
. - The forward and inverse Hadamard transforms are identical.
