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
)

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
ExceptionCondition
InvalidArgumentExceptionThe length of the input data signal is insufficient for the given decomposition level.
NullReferenceExceptionThe 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.
