FourierTransformer Constructor (Int32, FourierSign, FourierNormalization)

Initializes a new instance of the Fourier transformer with the given sign and normalization conventions.

Namespace: Meta.Numerics.SignalProcessing
Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4

Syntax

public FourierTransformer(
	int size,
	FourierSign signConvention,
	FourierNormalization normalizationConvention
)

Public Sub New ( 
	size As Integer,
	signConvention As FourierSign,
	normalizationConvention As FourierNormalization
)

public:
FourierTransformer(
	int size, 
	FourierSign signConvention, 
	FourierNormalization normalizationConvention
)

new : 
        size : int * 
        signConvention : FourierSign * 
        normalizationConvention : FourierNormalization -> FourierTransformer

Parameters

size: Type: SystemInt32
The series length of the transformer, which must be positive.
signConvention: Type: Meta.Numerics.SignalProcessingFourierSign
The sign convention of the transformer.
normalizationConvention: Type: Meta.Numerics.SignalProcessingFourierNormalization
The normalization convention of the transformer.

Remarks

There are multiple conventions for both the sign of the exponent and the overall normalization of Fourier transforms. The default conventions for some widely used software packages are summarized in the following table.

Software	Sign	Normalization
Meta.Numerics	Negative	None
Matlab	Negative	None
Mathmatica	Positive	Unitary
Numerical Recipies	Positive	None
