FindZero(Expression<Func<Vector<Double>, Double>>[], Vector<Double>)
Solves a system of nonlinear equations starting from an initial guess.
public static Vector<double> FindZero(
Expression<Func<Vector<double>, double>>[] targetFunctions,
Vector<double> initialGuess
)
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
Convergence | The algorithm failed to converge to a solution. |
FindZero(Expression<Func<Double, Double>>, Double)
Finds a zero of a function starting from an initial guess.
public static double FindZero(
Expression<Func<double, double>> targetFunction,
double initialGuess
)
Parameters
- targetFunction Expression<Func<Double, Double>>
- A lambda expression that represents a function of one variable that specifies the function on the left-hand side of the equation.
- initialGuess Double
- An initial guess for ther zero.
Return Value
DoubleThe best approximation to a zero of targetFunction.
Remarks
Use this method when you have very little information about the location of the zero.
Exceptions
Convergence | The algorithm failed to converge to a solution. |
FindZero(Expression<Func<Double, Double>>, Double, Double)

public static double FindZero(
Expression<Func<double, double>> targetFunction,
double lowerBound,
double upperBound
)
Parameters
- targetFunction Expression<Func<Double, Double>>
- A lambda expression that represents a function of one variable that specifies the function on the left-hand side of the equation.
- lowerBound Double
- The lower bound of the interval that contains the root.
- upperBound Double
- The upper bound of the interval that contains the root.
Return Value
DoubleThe best approximation to a zero of targetFunction.
Exceptions
Convergence | The algorithm failed to converge to a solution. |
