Prony |
Interpolation with a sum of Prony terms of the real part of a relaxation or retardation function in frequency domain.
Note that for a relaxation the real part is increasing with frequency (e.g. real part of mechanical modulus), whereas for a retardation the real part is decreasing with frequency (e.g. real part of electrical permittivity)

SyntaxC#
public class PronySeriesFrequencyDomainImaginaryPartInterpolation : PronySeriesInterpolationBase, IInterpolationFunctionOptions, IInterpolationCurveOptions, IEquatable<PronySeriesFrequencyDomainImaginaryPartInterpolation>
The PronySeriesFrequencyDomainImaginaryPartInterpolation type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PronySeriesFrequencyDomainImaginaryPartInterpolation | Initializes a new instance of the PronySeriesFrequencyDomainImaginaryPartInterpolation class |
Properties| Name | Description | |
|---|---|---|
 | AllowNegativePronyCoefficients |
If true, also negative Prony coefficients are allowed. The default value is false.
(Inherited from PronySeriesInterpolationBase) |
| IsRelaxation |
If true, the Prony terms model a relaxation process, i.e. a modulus, where the real part increases with frequency.
If false, the Prony terms model a retardation process, i.e. a susceptibility, where the real part decreases with frequency.

| NumberOfPoints |
If PointsPerDecade is 0, this property specifies a fixed number of Prony terms.
Else, if PointsPerDecade is > 0, this property specifies the maximum number of Prony terms.
(Inherited from PronySeriesInterpolationBase) |
| PointsPerDecade |
Gets the number of Prony terms per decade. If this value is <=0, the property NumberOfPoints specifiy a fixed number of Prony terms.
Else, if this property is > 0, it specify the number of Prony terms per decade, and NumberOfPoints only specifies the maximum number of Prony terms.

| RegularizationParameter |
Gets /sets the regularization parameter that controls the smoothing
of the resulting curve. The higher the parameter, the smoother the resulting curve will be.
(Inherited from PronySeriesInterpolationBase) |
| UseIntercept |
If true, besides of the Prony terms, additionally an intercept is fitted to the data.
(Inherited from PronySeriesInterpolationBase) |
| XMinimumMaximum |
Gets the minimum and maximum x values to be used. If this property is null, then the minimum and maximum x is determined automatically.
In time domain, the x values are times. In frequency domain, the x values are frequencies (frequencies, not circular frequencies!).
