Methods

	Name	Description
	Clone	Creates a deep copy of this FFT instance.
	CreateInverseFFT	Creates a backward FFT instance of this forward double complex 1D FFT.
	FFT(DoubleComplex)	Computes foward FFT of vin.
	FFT(DoubleComplexVector)	Computes the foward FFT of vin.
	FFT(DoubleComplex, DoubleComplex)	Computes foward FFT of vin and places the result in vout
	FFT(DoubleComplexVector, DoubleComplexVector)	Computes the foward FFT of vin and places the result in vout
	FFT(DoubleComplex, Int32, DoubleComplex, Int32)	Computes the forward FFT of vin and places the result in vout, where vin and vout contain offset signal data, vinoffset, voutoffset, respectively, from the [0] element.
	FFTInPlace(DoubleComplex)	Obsolete. Computes the forward FFT of each row in arrayinout and returns the results in-place.
	FFTInPlace(DoubleComplex)	Computes the in-place forward FFT of the signal vinout.
	FFTInPlace(DoubleComplexVector)	Computes the in-place forward FFT of the signal vinout.
	FFTInPlace(DoubleComplex, Int32)	Computes the in-place forward FFT of the signal vinout.
	FFTInPlaceArray	Computes the forward FFT of each row in arrayinout and returns the results in-place.
	ToString	Returns a String containing a summary of this FFT type. (Inherited from FFTBase.)

Fields

	Name	Description
	ipconfig_	In-place FFT configuration. (Inherited from FFTBase.)
	ofpconfig_	Out-of-place FFT configuration. (Inherited from FFTBase.)

Remarks

The forward FFT is defined to have a negative exponent in the transform with a default scale factor of 1.0. To gain greater efficiency in transforming sets of same-length signals, first arrange signals row-by-row in an array, and then use the FFTInPlace(DoubleComplex[,] arrayinout) method.
