Types

type Transform

type Transform struct {
	// contains filtered or unexported fields
}

func Daubechies4

func Daubechies4(s []float64, level int) *Transform

Daubechies4 returns the DWT with Daubechies 4 coeficients to level.

func (*Transform) GetCoefficients

func (t *Transform) GetCoefficients() [][]float64

GetCoefficients returns the coefficients of all transform levels

func (*Transform) GetDecomposition

func (t *Transform) GetDecomposition() []float64

GetDecomposition returns the vector containing the DWT decomposion

func (*Transform) GetDownSampledCoefficients

func (t *Transform) GetDownSampledCoefficients() [][]float64

GetDownSampledCoefficients returns the coefficients of all the levels downsampled to the length of the deepest level of the transform.
