The DoubleForward2DFFT type exposes the following members.

Constructors

	Name	Description
	DoubleForward2DFFT(FFT2DBase)	Constructs a forward 2D FFT instance by copying the configuration from another FFT instance.
	DoubleForward2DFFT(Int32, Int32)	Constructs a forward 2D FFT instance for double real signal vectors.

Properties

	Name	Description
	Columns	Gets the number of expected colums in FFT input array (Inherited from FFT2DBase)
	Dimension	Gets the FFT dimension; typically either 1, 2 or 3. (Inherited from FFT2DBase)
	Direction	Gets the direction of the FFT, either forward or backward. (Inherited from FFT2DBase)
	Domain	Gets the forward domain of signal data; either complex or real. (Inherited from FFT2DBase)
	ForwardScaleFactor	Gets or sets the forward scale factor of the FFT; The default is 1.0
	Precision	Gets the FFT precision; either float or double (Inherited from FFT2DBase)
	Rows	Gets the number of expected rows in FFT input array (Inherited from FFT2DBase)

Methods

	Name	Description
	Clone	Creates a deep copy of this FFT instance.
	FFT(Double, Double)	Computes the forward out-of-place FFT of vin.
	FFT(DoubleMatrix, DoubleMatrix)	Computes the foward FFT of vin and places the result in vout
	FFTInPlace(Double)	Computes the in-place forward FFT of the signal vinout.
	FFTInPlace(DoubleMatrix)	Computes the in-place forward FFT of the signal vinout.
	GetSignalReader(Double)	Generates the appropriate reader to unpack the packed complex conjugate symmetric FFT's computed by this class.
	GetSignalReader(DoubleMatrix)	Generates the appropriate reader to unpack the packed complex conjugate symmetric FFT's computed by this class.
	ToString	Returns a String containing a summary of this FFT type. (Inherited from FFT2DBase)

Fields

	Name	Description
	configColMajor_	Internal MKL configuration manager for column major arrays. The two configurations are identical in all ways except in how they interpret 2D array data. (Inherited from FFT2DBase)
	configRowMajor_	Internal MKL configuration manager for row major arrays. The two configurations are identical in all ways except in how they interpret 2D array data. (Inherited from FFT2DBase)

Remarks

The forward FFT is defined to have a negative exponent in the transform with a default scale factor of 1.0.
