void Jacobian(
	double[] x,
	double[,] jac
)

Sub Jacobian ( 
	x As Double(),
	jac As Double(,)
)

void Jacobian(
	array<double>^ x, 
	array<double,2>^ jac
)

abstract Jacobian : 
        x : float[] * 
        jac : float[,] -> unit 

Parameters

x

Type: SystemDouble
A double array which contains the point at which the Jacobian is to be evaluated. The contents of this array must not be altered by this function.

jac

Type: SystemDouble
A double matrix which, on return, contains the value of the Jacobian at x. The value of jac[i,j] is the derivative of f[i] with respect to x[j].
