| Forward | Computes the discrete Fourier transform of a real signal and returns the result. |
| Forward | Computes the discrete Fourier transform of a complex signal and returns the result. |

ForwardTransform(ArraySlice<Complex<Double>>, ArraySlice<Complex<Double>>)
Computes the discrete Fourier transform of a complex signal.
public override void ForwardTransform(
ArraySlice<Complex<double>> input,
ArraySlice<Complex<double>> output
)Parameters
- input ArraySlice<Complex<Double>>
- A complex number array containing the input signal.
- output ArraySlice<Complex<Double>>
- A complex number array to hold the transformed signal.
Exceptions
| InvalidOperationException | The Fourier transform implementation is not configured
to accept complex input.
-or- input and output are the same, but the Fourier transform implementation is not configured to handle in-place transforms. |
| ArgumentNullException | input is null.
-or- output is null. |
ForwardTransform(ArraySlice<Double>, ArraySlice<Complex<Double>>)
Computes the discrete Fourier transform of a real signal.
public override void ForwardTransform(
ArraySlice<double> input,
ArraySlice<Complex<double>> output
)Parameters
- input ArraySlice<Double>
- A Double array containing the input signal.
- output ArraySlice<Complex<Double>>
- A complex number array to hold the transformed signal.
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 ComplexConjugateSignalVector<T> class to obtain a complex vector that represents the complete signal.
Exceptions
| InvalidOperationException | The Fourier transform implementation is not configured to accept real input. |
| ArgumentNullException | input is null.
-or- output is null. |
