signalsmith::mix::Hadamard< Sample, size > Class Template Reference

#include <mix.h>

Detailed Description

template<typename Sample, int size = -1>
class signalsmith::mix::Hadamard< Sample, size >

Hadamard: high mixing levels, N log(N) operations.

Static Methods
template<class Data>
static void	inPlace (Data &&data)
	Applies the matrix, scaled so it's orthogonal.
static Sample	scalingFactor ()
	Scaling factor applied to make it orthogonal.
template<class Data, int startIndex = 0>
static void	unscaledInPlace (Data &&data)
	Skips the scaling, so it's a matrix full of 1s.

Method Details

inPlace()

template<typename Sample, int size = -1>

template<class Data>

static void signalsmith::mix::Hadamard< Sample, size >::inPlace ( Data && data )

inlinestatic

Applies the matrix, scaled so it's orthogonal.

scalingFactor()

template<typename Sample, int size = -1>

static Sample signalsmith::mix::Hadamard< Sample, size >::scalingFactor ( )

inlinestatic

Scaling factor applied to make it orthogonal.

TODO: test for C++20, or whatever makes this constexpr. Maybe a #define in common.h?

unscaledInPlace()

template<typename Sample, int size = -1>

template<class Data, int startIndex = 0>

static void signalsmith::mix::Hadamard< Sample, size >::unscaledInPlace ( Data && data )

inlinestatic

Skips the scaling, so it's a matrix full of 1s.
