BoundedOneVariableFunctionFitterMFit(DoubleVector, DoubleVector, DoubleVector, DoubleVector, DoubleVector) Method

Fits a function to the specified points.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
Syntax
Copy
public DoubleVector Fit(
	DoubleVector xValues,
	DoubleVector yValues,
	DoubleVector initialParameters,
	DoubleVector parameterLowerBounds,
	DoubleVector parameterUpperBounds
)

Parameters

xValues  DoubleVector
parameters values of the points to fit.
yValues  DoubleVector
yValues values of the points to fit.
initialParameters  DoubleVector
The starting function parameters.
parameterLowerBounds  DoubleVector
Lower bounds for the solution parameters p, such that parameterLowerBounds[i] <= p[i].
parameterUpperBounds  DoubleVector
Upper bounds for the solution parameters p, such that parameterUpperBounds[i] >= p[i].

Return Value

DoubleVector
The parameters of the function at the minimum.
Exceptions
ExceptionCondition
InvalidArgumentException Thrown if the vectors of parameters and yValues values have different lengths, or if the number of points is not greater than or equal to the number of function parameters.
Remarks
In the space of the function parameters, begining at the specified starting point (initialParameters), finds a minimum (possibly local) with respect to the sum of the squared residuals, where residuals[i] = ( yValues[i] - f( currentParameters, xValues[i] )^2.
Note that problems can have multiple local minima. Trying different initial points is recommended for better solutions.
