Description: Newton-Raphson法的介绍，包括原理，迭代方程，收敛性，优缺点，以及一个应用示范-The Newton-Raphson method, or Newton Method, is a powerful technique
for solving equations numerically. Like so much of the di erential calculus,
it is based on the simple idea of linear approximation. The Newton Method,
properly used, usually homes in on a root with devastating eciency.
The essential part of these notes is Section 2.1, where the basic formula
is derived, Section 2.2, where the procedure is interpreted geometrically,
and|of course|Section 6, where the problems are. Peripheral but perhaps
interesting is Section 3, where the birth of the Newton Method is described. Platform: |
