Single step discrete wavelet reconstruction.

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

Syntax

public double[] IDWT(
	double[] approx,
	double[] details,
	bool sizeMatch = true
)

Public Function IDWT ( 
	approx As Double(),
	details As Double(),
	Optional sizeMatch As Boolean = true
) As Double()

public:
array<double>^ IDWT(
	array<double>^ approx, 
	array<double>^ details, 
	bool sizeMatch = true
)

member IDWT : 
        approx : float[] * 
        details : float[] * 
        ?sizeMatch : bool 
(* Defaults:
        let _sizeMatch = defaultArg sizeMatch true
*)
-> float[]

Parameters

approx Double: The DWT approximation array.
details Double: The DWT details array.
sizeMatch Boolean (Optional): If sizeMatch is false then the approximation vector must be one element longer than the details vector. Useful for reconstruction.

Return Value

Double
The reconstructed signal.

Exceptions

Exception	Condition
InvalidArgumentException	The approximation and details arrays must have the same length when sizeMatch is true.
InvalidArgumentException	The approximation array length must be one greater than the details array length when sizeMatch is false.
InvalidArgumentException	The approximation and details arrays must have a length of at least half the wavelet length.
ArgumentNullException	Both approximation and details arrays must be non-null.
