Havriliak |
Havriliak-Negami retardation function to fit modulus values. This function essentially implements the same as HavriliakNegamiSusceptibility,
but the parametrization is different (modulus values instead of susceptibilities).

public class HavriliakNegamiModulusRetardation : IFitFunction, IImmutable
The HavriliakNegamiModulusRetardation type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | HavriliakNegamiModulusRetardation | Initializes a new instance of the HavriliakNegamiModulusRetardation class. |
Properties| Name | Description | |
|---|---|---|
 | InvertViscosity | Gets a value indicating whether the viscosity parameter is inverted (i.e. fluidity is used). |
| LogarithmizeResults | Indicates whether the real and imaginary parts of the dependent variable should be logarithmized (decadic logarithm). |
| NumberOfDependentVariables | Number of dependent variables (i.e. y, in Altaxo this is commonly called v (like value)). |
| NumberOfIndependentVariables | Number of independent variables (i.e. x). |
| NumberOfParameters | Number of parameters of this fit function. |
| UseFlowTerm | Gets a value indicating whether a flow term is included in the model. |
| UseFrequencyInsteadOfOmega | Gets a value indicating whether the independent variable is the frequency instead of circular frequency (omega). |
Methods| Name | Description | |
|---|---|---|
 | CreateLg10ModulusOfFrequency | |
| CreateLg10ModulusOfOmega | |
| CreateModulusOfFrequency | |
| CreateModulusOfOmega | |
| DefaultParameterValue | Returns a default parameter value. You must ensure that the fit function would generate values with those default parameters. |
| DefaultVarianceScaling | Returns the default variance scaling for the dependent variable i. |
| DependentVariableName | Returns the ith dependent variable name. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Evaluate(Double, Double, Double) | This evaluates a function value. |
| Evaluate(IROMatrixDouble, IReadOnlyListDouble, IVectorDouble, IReadOnlyListBoolean) | Evaluates the function values at multiple x-points. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetParameterBoundariesHardLimit | Gets the parameter boundaries that are really a hard limit, i.e. outside those limits, the function would probably evaluate NaN values, or makes no sense. |
| GetParameterBoundariesSoftLimit | Gets the intended parameter boundaries. This are soft limits, boundaries so that the intended purpose of the fit function is fullfilled. Example: in the exponential decay Exp(-a*t) a is intended to be positive. This is a soft limit, and not a hard limit, because a could be also negative, and the fit nevertheless would succeed. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| IndependentVariableName | Returns the ith independent variable name. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ParameterName | Returns the ith parameter name. |
| ToString | Returns a string that represents the current object. (Overrides ObjectToString) |
| WithInvertViscosity | Returns a new instance with the InvertViscosity property set to the specified value. |
| WithLogarithmizeResults | Returns a new instance with the LogarithmizeResults property set to the specified value. |
| WithUseFlowTerm | Returns a new instance with the UseFlowTerm property set to the specified value. |
| WithUseFrequencyInsteadOfOmega | Returns a new instance with the UseFrequencyInsteadOfOmega property set to the specified value. |
