Fft2D<T> Class

Represents a discrete 2-dimensional Fourier Transform implementation.

Definition

Namespace: Numerics.NET.SignalProcessing
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.4
C#
public abstract class Fft2D<T> : FftBase<T>
Inheritance
Object  →  FftBase<T>  →  Fft2D<T>
Derived

Type Parameters

T

Remarks

Use the Fft2D<T> class to perform one or more discrete Fourier Transforms of a specific size. An FFT implementation must be created for each combination of size of FFT and domain. The FftDomain property is an FftDomain value and can be real or complex. The length in each dimension is an integer greater than 0. It can be accessed through the GetLength(Int32) method.

Some implementations use unmanaged resources. To ensure that all resources are released properly, you should call the Dispose() method when you are done with the object.

This class is abstract and cannot be instantiated. Instead, use one of the methods of an FftOperations<T> to construct an Fft2D<T> object from that provider.

Constructors

Fft2D<T> Constructs a new FFT transform implementation.
