This program solves the following equation using bi-section method.

Launch Matlab by either clicking twice on the Matlab icon on your desktop or by selecting: Start Programs Matlab Matlab. The main window is the MATLAB Command Window, where you write your instructions.

学会不同搜索法（最速下降法，共轭梯度法，牛顿法，拟牛顿法）的计算步骤； 比较不同搜索法（最速下降法，共轭梯度法，牛顿法，拟牛顿法）的优缺点。 (Institute of the different search method (steepest descent method, conjugate gradient method, Newton method, quasi-Newton method) for calculating steps compare different search method (steepest descent method, conjugate gradient method, Newton method, quasi-Newton method) the advantages and disadvantages.)

Unit Step Signal Generation

Arnijo准则非精确搜索程序，可以作为其他优化程序的子程序调用(Arnijo guidelines inexact search program, you can call a subroutine other optimization procedures)

single input single output system

该程序用来实现Turbo编解码，而Turbo码是一种信道编码、且是一种纠错码，可以保证信息的传输质量,本程序是用matlab实现的!(The procedure used for Turbo coding and decoding, while the Turbo code is a channel coding, and is an error-correcting codes, can guarantee the quality of information transmission, the process is achieved using matlab!)

齿轮形状可调，可分布不同齿形，大大节约作图时间，希望大家支持改进(The gear shape adjustable spread toothed significant savings plotting time, I hope you will support improved)
