Crate nrfind [−] [src]

nrfind is a crate for finding the roots of arbitrary functions whose derivatives are known by the Newton-Rahpson method.

Functions

find_root	Uses the Newton-Raphson method to find roots for `function` given that `derivative` is the first derivative of `function`. If `max_iterations` is reached without the error falling below the given `acceptable_err`, `nrfind` will return `None`.
find_sqrt	Find the square root of a given `radicand` to within a given `acceptable_err` by the Newton-Rahpson method, initial guess `x0`, and give up after `max_iterations` (in which case `None` is returned).
