Imaginary part of the Fourier transformed derivative of the Kohlrausch function for low frequencies.
Namespace: Altaxo.CalcAssembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3572.0 (4.8.3572.0)
Syntaxpublic static double Im2(
double beta,
double z
)
Parameters
- beta Double
- Beta parameter.
- z Double
- Circular frequency.
Return Value
DoubleImaginary part of the Fourier transformed derivative of the Kohlrausch function for low frequencies, or
NaN if the series does not converge.
RemarksThis is the imaginary part of the Fourier transform (in Mathematica notation): Im[Integrate[D[Exp[-t^beta],t]*Exp[-I w t],{t, 0, Infinity}]]. The sign of
the return value here is positive!.
