Kohlrausch |
Kohlrausch function in the frequency domain to fit modulus spectra. This is the inverse of the retardation spectra,
i.e. tau is the retardation time (and not the relaxation time!).

public class KohlrauschModulusRetardation : IFitFunction
The KohlrauschModulusRetardation type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | KohlrauschModulusRetardation | Initializes a new instance of the KohlrauschModulusRetardation class. |
Properties| Name | Description | |
|---|---|---|
 | InvertViscosity | Gets a value indicating whether to invert the viscosity (then a general fluidity is used as parameter). |
| LogarithmizeResults | Indicates whether the real and imaginary part 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 to use a flow term. |
| UseFrequencyInsteadOfOmega | Gets a value indicating whether to use the frequency instead of 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) |
| OnChanged | Called when anything in this fit function has changed. |
| 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. |
