DoubleMultiVariableFunctionJacobian(DoubleVector, DoubleMatrix) Method

Virtual method for evaluating the Jacobian of the function at the given point.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public virtual void Jacobian(
	DoubleVector x,
	ref DoubleMatrix jac
)

Public Overridable Sub Jacobian ( 
	x As DoubleVector,
	ByRef jac As DoubleMatrix
)

public:
virtual void Jacobian(
	DoubleVector^ x, 
	DoubleMatrix^% jac
)

abstract Jacobian : 
        x : DoubleVector * 
        jac : DoubleMatrix byref -> unit 
override Jacobian : 
        x : DoubleVector * 
        jac : DoubleMatrix byref -> unit

Parameters

x DoubleVector: The point to evaluate the Jacobian at.
jac DoubleMatrix: The Jacobian at x.

Remarks

The default implementation here approximates the Jacobian using a central difference algorithm. The size of the delta used can be controlled by the CentralDifferenceDelta property. Deriving classes should override this method if an explicit formula for the Jacobian is available.
