f_joint_root
Description
Calculates the root of a function given an initial value and a function to calculate its derivatives.
Usage
f_joint_root(f, start, tol = 1e-08, n.max = 1000)
Arguments
f |
function: A function that receives a vector and return a vector of the same size and a matrix representing its derivatives. |
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:
root vector: The solution for the system f(x)=0.
f.root vector: The function f evaluated at the root.
iter numeric: The number of steps taken.
