DoubleSWTDecompose Method

Decompose the signal into approximation and details with the SWT.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public Tuple<double[,], double[,]> Decompose(
	int N
)

Public Function Decompose ( 
	N As Integer
) As Tuple(Of Double(,), Double(,))

public:
Tuple<array<double,2>^, array<double,2>^>^ Decompose(
	int N
)

member Decompose : 
        N : int -> Tuple<float[,], float[,]>

Parameters

N Int32: Compute the wavelet decomposition to level N.

Return Value

TupleDouble, Double
Returns a Tuple<double[,], double[,]> with the item1 array containing N detail row vectors, and item2 containing N approximate row vectors.

Exceptions

Exception	Condition
InvalidArgumentException	The length of the input data signal is insufficient for the given decomposition level.
NullReferenceException	The Signal property must first be assigned to a valid data array.

Remarks

This scheme follows the "filtering tree" that saves the high-pass filtered transformed signal as approximation coefficients and the low pass filtered transformed signal as detailed coefficients.
