The FloatComplexBackward2DFFT type exposes the following members.

Constructors

	Name	Description
	FloatComplexBackward2DFFT(FFT2DBase)	Constructs a backward 2D FFT instance by copying the configuration from another FFT instance.
	FloatComplexBackward2DFFT(Int32, Int32)	Constructs a backward 2D FFT instance for float complex signal vectors.

Properties

	Name	Description
	BackwardScaleFactor	Gets or sets the backward scale factor of the FFT; The default is 1.0
	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)
	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.
	CreateInverseFFT	Creates a forward FFT instance of this backward float complex 2D FFT.
	FFT(FloatComplex, FloatComplex)	Computes backward 2D FFT of min and places the result in mout
	FFT(FloatComplexMatrix, FloatComplexMatrix)	Computes the backward 2D FFT of min and places the result in mout
	FFTInPlace(FloatComplex)	Computes the in-place backward 2D FFT of the signal minout.
	FFTInPlace(FloatComplexMatrix)	Computes the in-place backward 2D FFT of the signal minout.
	SetScaleFactorByLength	Sets the backward FFT scale factor to 1/Rows*Cols.
	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 positive exponent in the transform with a default scale factor of 1.0.
