)

Parameters

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, includes an offset term (interpreted as retardation time 0).

withFlowTerm  Boolean

If set to true, includes a flow term (fluidity, conductivity).

isRelativePermittivitySpectrum  Boolean

If set to true, indicates that the fitted spectrum is a dielectric spectrum of relative permittivities.

flowTermScale  Double

Scale factor used for the flow term basis function.

allowNegativeCoefficients  Boolean

If true, allows negative Prony coefficients.

taus  Double

The retardation times (tau values) used for the Prony terms.

X  MatrixDouble

The design matrix (including optional regularization rows).

y  MatrixDouble

The target vector (including optional regularization entries).
