public static Vector<double> FindZero(
this Func<Vector<double>, double>[] targetFunctions,
Vector<double> initialGuess
)
Parameters
- targetFunctions Func<Vector<Double>, Double>[]
- An array of delegates 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.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type Func<Vector<Double>, Double>[]. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).Remarks
Use this method when you have very little information about the location of the zero.
