DoubleSWTWaveletCoefficients Method

Provides access to the details and approximation vectors. All details and approximation vectors are the same length with a SWT signal decomposition.

Syntax

public double[] WaveletCoefficients(
	DiscreteWaveletTransformWaveletCoefficientType type,
	int N
)

Public Function WaveletCoefficients ( 
	type As DiscreteWaveletTransformWaveletCoefficientType,
	N As Integer
) As Double()

public:
array<double>^ WaveletCoefficients(
	DiscreteWaveletTransformWaveletCoefficientType type, 
	int N
)

member WaveletCoefficients : 
        type : DiscreteWaveletTransformWaveletCoefficientType * 
        N : int -> float[]

type DiscreteWaveletTransformWaveletCoefficientType: The wavelet coefficient type, either details or approximation.
N Int32: Decomposition level needed, starting with N = 1 and continuing to the maximum level of decomposition computed.

Double
The detail or approximation vector at level N.

Exceptions

Exception	Condition
NMathException	A signal Decompose() must be completed before any signal details vectors can be accessed.
InvalidArgumentException	A level of signal decomposition has been requested that is beyond the maximum level of signal decomposition available.

Remarks

Similar to MATLAB's wrcoef.
