public override Fft2D<double> Create2DRealFft(
	int rowCount,
	int columnCount
)

Visual Basic

Public Overrides Function Create2DRealFft ( 
	rowCount As Integer,
	columnCount As Integer
) As Fft2D(Of Double)

C++/CLI

public:
virtual Fft2D<double>^ Create2DRealFft(
	int rowCount, 
	int columnCount
) override

abstract Create2DRealFft : 
        rowCount : int * 
        columnCount : int -> Fft2D<float> 
override Create2DRealFft : 
        rowCount : int * 
        columnCount : int -> Fft2D<float>

Parameters

rowCount Int32: The number of rows.
columnCount Int32: The number of columns.

Return Value

Fft2D<Double>
An Fft<T> object that can be used to compute an FFT of dimensions equal to rowCount by columnCount.

Remarks

Fft<T> objects may use unmanaged memory and other resources. You should always call the dispose method before the last reference to an Fft<T> object is released.

Exceptions

ArgumentOutOfRangeException

The total number of elements is greater than 2³¹-1.
