FloatSymmetricBackward1DFFTFFT(Single, Int32, Single) Method

Computes the backward out-of-place FFT of vin and places the result in vout, where vin and vout contain offset signal data, vinoffset, voutoffset, respectively, from the [0] element.

Syntax

Copy

public void FFT(
	float[] vin,
	int vinoffset,
	float[] vout
)

Public Sub FFT ( 
	vin As Single(),
	vinoffset As Integer,
	vout As Single()
)

public:
void FFT(
	array<float>^ vin, 
	int vinoffset, 
	array<float>^ vout
)

member FFT : 
        vin : float32[] * 
        vinoffset : int * 
        vout : float32[] -> unit

Parameters

vin Single: The input signal data.
vinoffset Int32: Offset to the start of the signal data.
vout Single: The FFT of vin.

Exceptions

Exception	Condition
InvalidArgumentException	Thrown when the signal data is shorter than this FloatSymmetricBackward1DFFT instance.
InvalidArgumentException	Thrown if the output array, vout is not large enough to contain the resultant FFT.

Remarks

For example, if vinoffset = 2, the FFT will start computing with the vin[2] data element of vin, and end at vin[2+Length-1]..
