Managed Fft.Forward Transform Method
Definition
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.2
Overload List
ForwardTransform(ReadOnlySpan<Complex<Double>>, Int32, Span<Complex<Double>>, Int32)
public override void ForwardTransform(
ReadOnlySpan<Complex<double>> input,
int inputStride,
Span<Complex<double>> output,
int outputStride
)
Parameters
Remarks
The output is stored in a compact format to take advantage of the symmetry properties of a real Fourier transform. Specifically, output contains only the first n/2+1 terms of the transformed signal. Use the complex Span<T> class to obtain a complex vector that represents the complete signal.
Exceptions
Invalid | The Fourier transform implementation is not configured to accept real input. |
Argument | input is null. -or- output is null. |
Dimension | The length of input does not equal the length of output. |
