Vogel |
Represents the Vogel-Fulcher law to describe the temperature dependence of times, viscosities, etc. in glass forming substances,
i.e. quantities which decrease with increasing temperature.

public class VogelFulcherLawTime : IFitFunction, IImmutable
The VogelFulcherLawTime type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | VogelFulcherLawTime | Initializes a new instance of the VogelFulcherLawTime class with default Kelvin units. |
| VogelFulcherLawTime(TemperatureRepresentation, TemperatureRepresentation, TemperatureRepresentation) | Initializes a new instance of the VogelFulcherLawTime class with the provided temperature unit representations. |
Properties| Name | Description | |
|---|---|---|
 | IndependentVariableRepresentation | Gets or sets the temperature unit representation used for the independent variable (temperature). |
| 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. |
| ParameterBRepresentation | Gets the temperature unit representation used for the parameter B. |
| ParameterT0Representation | Gets the temperature unit representation used for the parameter T0. |
Methods| Name | Description | |
|---|---|---|
 | CreateDefault | Factory method used by discovery to create a default instance of this fit function. |
| 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, IReadOnlyListDouble) | Evaluates the Vogel-Fulcher law for time-like quantities at the specified temperature. |
| 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 fit function.
(Overrides ObjectToString) |
| WithIndependentVariableRepresentation | Returns a new instance with the provided independent variable temperature representation. |
| WithParameterBRepresentation | Returns a new instance with the provided B parameter temperature representation. |
| WithParameterT0Representation | Returns a new instance with the provided T0 parameter temperature representation. |
