PronySeriesRetardationEvaluateTimeDomain(IReadOnlyListDouble, IReadOnlyListDouble, Double, Double, Int32, Boolean, Boolean, Double, Boolean) Method

public static PronySeriesRetardationResult EvaluateTimeDomain(
	IReadOnlyList<double> xarr,
	IReadOnlyList<double> yarr,
	double tmin,
	double tmax,
	int numberOfRetardationTimes,
	bool withIntercept,
	bool withFlowTerm,
	double regularizationLambda,
	bool allowNegativeCoefficients = false
)

Parameters

xarr  IReadOnlyListDouble

The x-values of the signal (all elements must be positive).

yarr  IReadOnlyListDouble

The y-values of the signal.

tmin  Double

The smallest Retardation time (tau of the first Prony term).

tmax  Double

The largest Retardation time (tau of the last Prony term).

numberOfRetardationTimes  Int32

The number of Retardation times (number of Prony terms).

withIntercept  Boolean

If set to true, an offset term is added. This term can be considered to have a retardation time of zero.

withFlowTerm  Boolean

If set to true, a flow term (fluidity, conductivity) is also fitted.

regularizationLambda  Double

A regularization parameter to smooth the resulting array of Prony terms.

allowNegativeCoefficients  Boolean  (Optional)

Normally, in a Prony series only nonnegative coefficients are allowed. Set this parameter to true to allow also negative coefficients.
