牛顿迭代的c语言程序，牛顿迭代法是求方程根的重要方法之一，其最大优点是在方程f(x) = 0的单根附近具有平方收敛，而且该法还可以用来求方程的重根、复根,此时线性收敛，但是可通过一些方法变成超线性收敛。另外该方法广泛用于计算机编程中。

-Newton iteration c language program, Newton' s law is an important way to find one root of the equation, its greatest advantage is in the equation f (x) = 0 has a single root of the square near the convergence, and the method can also be used to find equation re-root, complex roots, then the linear convergence, but by some of the ways to become super-linear convergence. Also the method widely used in computer programming.
