Type Secant

Namespace MathNet.Numerics.RootFinding

Pure Secant root-finding algorithm without any recovery measures in cases it behaves badly. The algorithm aborts immediately if the root leaves the bound interval.

Static Functions

Public Static Functions

double FindRoot(Func<double, double> f, double guess, double secondGuess, double lowerBound, double upperBound, double accuracy, int maxIterations)

Find a solution of the equation f(x)=0.
Parameters
Func<double, double> f

The function to find roots from.

double guess

The first guess of the root within the bounds specified.

double secondGuess

The second guess of the root within the bounds specified.

double lowerBound

The low value of the range where the root is supposed to be. Aborts if it leaves the interval. Default MinValue.

double upperBound

The high value of the range where the root is supposed to be. Aborts if it leaves the interval. Default MaxValue.

double accuracy

Desired accuracy. The root will be refined until the accuracy or the maximum number of iterations is reached. Default 1e-8. Must be greater than 0.

int maxIterations

Maximum number of iterations. Default 100.

Return
double

Returns the root with the specified accuracy.
