DoubleComplexForward1DFFTFFT(DoubleComplex, Int32, DoubleComplex, Int32) Method

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.

Copy

public void FFT(
	DoubleComplex[] vin,
	int vinoffset,
	ref DoubleComplex[] vout,
	int voutoffset
)

Public Sub FFT ( 
	vin As DoubleComplex(),
	vinoffset As Integer,
	ByRef vout As DoubleComplex(),
	voutoffset As Integer
)

public:
void FFT(
	array<DoubleComplex>^ vin, 
	int vinoffset, 
	array<DoubleComplex>^% vout, 
	int voutoffset
)

member FFT : 
        vin : DoubleComplex[] * 
        vinoffset : int * 
        vout : DoubleComplex[] byref * 
        voutoffset : int -> unit

Parameters

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

Exceptions

Exception	Condition
MismatchedSizeException	Thrown when the signal data is shorter than this DoubleComplexForward1DFFT 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]..
