二进制LDPC码的一种构造方法mackey构造，是学习LDPC码的基础(Binary LDPC code construction method mackey construction, is to learn the basis of LDPC codes)

说明：  实现了用超声波测量以及形成图像 对相关信号进行模拟仿真(Achieved the formation of images using ultrasound measurements, and simulation of the relevant signals)

This is a self developed Finite Element Method code.This code is written in Object oriented matlab programing lanuage. It is well designed. It is a good code for you to learn how to write object oriented matlab code. If you are interested in matlab programming or FEM simulation. Please feel free to contact the author.

该文给出了一种利用matlab系统实现频谱分析与显示的方法。该方法对语音信号进行基于FFT的短时频谱分析，频谱图的伪彩色映射及显示。(This paper presents a system implementation using matlab spectrum analysis and display methods. The method is based on the speech signal short-time FFT spectrum analysis, spectrum and display pseudo-color mapping.)

混沌优化，用于求解非凸优化，算法运算速度快(Chaos optimization, for solving non-convex optimization, fast algorithm)

滤波器设计代码，很好有用希望大家能够用，多多交流(Filter design code, a good hope that we can be useful, and more exchanges)

遗传算法的算法实例，我是一个初学者，通过研究这些现成的代码，感觉对自己挺有帮助(It is helpful for those who study MATLAB first time)
