说明：  牛顿拉富生线搜索是解决方程的程序与quasi-Newton-Raphson方法加速了线搜索算法。要解决的方程可以包括向量,除了标量,用MATLAB编程语言写的.
(Newton Raphson Line Search is a program for the solution of equations with the quasi-Newton-Raphson method accelerated by a line search algorithm. The equation to be solved can include vectors, except for scalars. It is written in MATLAB programming language and is available as source code distributed under a BSD-style license (see License.txt). Type help line_search and help fun to view the instructions for usage in MATLAB.)
