f_root {kDGLM}R Documentation

f_root

Description

Calculates the root of a function given an initial value and a function to calculate its derivatives.

Usage

f_root(f, df, start, tol = 1e-08, n.max = 1000)

Arguments

f

function: A function that receives a vector and return a vector of the same size.

df

function: A function that receives a vector and return the derivatives of f with respect to its arguments (if f returns a vector, it must be a matrix).

start

vector: The initial value to start the algorithm.

tol

numeric: The tolerance for the solution.

n.max

numeric: The maximum number of iterations allowed.

Value

A list containing:
