GetEquationSolver(Expression<Func<Vector<Double>, Double>>[], Vector<Double>)
Finds a zero of a function starting from an initial guess.
public static EquationSystemSolver GetEquationSolver(
Expression<Func<Vector<double>, double>>[] targetFunctions,
Vector<double> initialGuess
)
Parameters
- targetFunctions Expression<Func<Vector<Double>, Double>>[]
- A delegate that represents a multivariate function returning a vector that specifies the function on the left-hand side of the equation.
- initialGuess Vector<Double>
- An initial guess for ther zero.
Return Value
EquationSystemSolverThe best approximation to a zero of targetFunctions.
Remarks
Use this method when you have very little information about the location of the zero, but you need more control over the solution process. For example, you may want to specify a different RelativeTolerance.
GetEquationSolver(Expression<Func<Double, Double>>, Double)
Returns an EquationSolver suitable for solving an equation using the specified information.
public static EquationSolver GetEquationSolver(
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
EquationSolverAn EquationSolver object that is set up to solve an equation for the specifed target function.
Remarks
Use this method when you have very little information about the location of the zero, but you need more control over the solution process. For example, you may want to specify a different RelativeTolerance.
GetEquationSolver(Expression<Func<Double, Double>>, Double, Double)
Finds a zero of a function when the solution is known to lie within a specified interval.
public static EquationSolver GetEquationSolver(
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
EquationSolverThe best approximation to a zero of targetFunction, but you need more control over the solution process. For example, you may want to specify a different RelativeTolerance.
