MultiVariableFunctionFitterMFit Method

Fits a function to the specified points.

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


xValues  DoubleMatrix
parameters values of the points to fit. Each row in the matrix is an x-value of the points to fit.
yValues  DoubleVector
yValues values of the points to fit.
initialParameters  DoubleVector
The starting function parameters.

Return Value

The parameters of the function at the minimum.
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.
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. You must supply at least as many points to fit as your function has parameters.
Note that problems can have multiple local minima. Trying different initial points is recommended for better solutions.
