Properties
 NameDescription
Public propertyNumberOfDependentVariables Number of dependent variables (i.e. y, in Altaxo this is commonly called v (like value)).
Public propertyNumberOfIndependentVariables Number of independent variables (i.e. x).
Public propertyNumberOfParameters Number of parameters of this fit function.
Public propertyPolynomialOrder_LeftSegment Gets the order of the left polynomial segment.
Public propertyPolynomialOrder_RightSegment Gets the polynomial order of the right segment.

Methods
 NameDescription
Public methodStatic memberCreateTwoPolynomialSegments_1_1Creates a new instance of TwoPolynomialSegments with linear segments.
Public methodDefaultParameterValue Returns a default parameter value. You must ensure that the fit function would generate values with those default parameters.
Public methodDefaultVarianceScaling Returns the default variance scaling for the dependent variable i.
Public methodDependentVariableName Returns the ith dependent variable name.
Public methodEqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
Public methodEvaluate(Double, Double, Double) This evaluates a function value.
Public methodEvaluate(IROMatrixDouble, IReadOnlyListDouble, IVectorDouble, IReadOnlyListBoolean) Evaluates the function values at multiple x-points.
Public methodStatic memberEvaluate(Double, Double, Double, ReadOnlySpanDouble, ReadOnlySpanDouble) Evaluates the function for the specified x value.
Public methodEvaluateDerivative Evaluates the gradient of the function with respect to the parameters.
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
Public methodGetHashCodeServes as the default hash function.
(Inherited from Object)
Public methodGetParameterBoundariesHardLimit 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.
Public methodGetParameterBoundariesSoftLimit 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.
Public methodGetTypeGets the Type of the current instance.
(Inherited from Object)
Public methodIndependentVariableName Returns the ith independent variable name.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Public methodParameterName Returns the ith parameter name.
Public methodToStringReturns a string that represents the current object.
(Inherited from Object)
Public methodWithPolynomialOrder_LeftSegment Creates a new instance with the provided order for the left polynomial segment.
Public methodWithPolynomialOrder_RightSegment Creates a new instance with the provided order for the right polynomial segment.
