FFTConfiguration Class

FFTConfiguration contains all of the FFT configuration state to efficiently compute a FFT. This class is typically used in conjunction with the GeneralxDFFT set of classes to configure FFT's with offset and strided signal data.

The FFTConfiguration type exposes the following members.

Constructors

	Name	Description
	FFTConfiguration	Creates an instance of a 1D FFT configuration. This configuration instance can then be used to create a DoubleGeneral1DFFT instance.

Properties

	Name	Description
	BackwardScaleFactor	Gets or sets the backward scale factor
	DataOffset	Gets or sets the offset to the start of the signal. If the data has no offset, the DataOffset is 0 by default.
	DataStride	Gets or sets the stride of data within each signal. If the data is packed, the DataStride is 1 by default.
	Dimension	Gets FFT dimension
	Direction	Gets or sets the forward or backward direction of the FFT transform.
	Domain	Gets forward domain of signal data; either complex or real.
	ForwardScaleFactor	Gets or sets the forward scale factor
	InPlace	Gets or sets the resultant storage location. Set to true for in-place computation, false for out-of-place computation.
	Length	Gets the length of the expected signal data. Signal data length can be arbitrary. No radix limitations.
	Precision	Gets the FFT precision; either float or double
	SignalCount	Gets or sets the number of signals to transform. SignalCount is greater than one when transforming sets of signals in an array.
	SignalStride	Gets or sets the stride of signals in an array of multiple signals.
