public static Vector<double> FindZero(
	Expression<Func<Vector<double>, double>>[] targetFunctions,
	Vector<double> initialGuess
)

Visual Basic

Public Shared Function FindZero ( 
	targetFunctions As Expression(Of Func(Of Vector(Of Double), Double))(),
	initialGuess As Vector(Of Double)
) As Vector(Of Double)

C++/CLI

public:
static Vector<double>^ FindZero(
	array<Expression<Func<Vector<double>^, double>^>^>^ targetFunctions, 
	Vector<double>^ initialGuess
)

static member FindZero : 
        targetFunctions : Expression<Func<Vector<float>, float>>[] * 
        initialGuess : Vector<float> -> Vector<float>

Parameters

targetFunctions Expression<Func<Vector<Double>, Double>>[]: An array of lambda expressions that represent a multivariate function that specify the left-hand sides of the equation.
initialGuess Vector<Double>: An initial guess for the solution.

Return Value

Vector<Double>
The best approximation to a zero of targetFunctions.

Remarks

Use this method when you have very little information about the location of the zero.

Exceptions

ConvergenceException
