This m file performs the CDMA coding and decoding.

优化设计中常用的 牛顿法 和二次插值法 应用十分广泛 求解凸函数的极值和极值点问题(Commonly used to optimize the design of the Newton' s law and application of quadratic interpolation method for solving a wide range of convex functions and extreme points of the extremal problem)

说明：  提供坐标轴缩放、转换、设置的matlab环境模版。(Provide axes scaling, conversion, set the template of the matlab environment.)

实现基于PSO的三维图形的极值计算，并显示中间的搜索过程。(Implementation is based on PSO to calculate the extremum of 3 d graphics and display in the middle of the search process.)

Maximum Likelihood Decoding

较简单的车牌定位方法,并用matlab实现,该程序得到我老师的好评!(A simpler method of license plate location and use matlab implementation, the program received high praise from my teacher!)

MATLAB 下的LDPC编码解码，自己编写，在7/0下通过验证(Decoding LDPC codes under MATLAB, I have written, in 7/0, validated)

对于三对角矩阵有个matlab的编程就绝方法其中有些数据是需要自己填补的(.He is in a weakened condition. 2.He is in good physical condition. 3.I have been feeling really run down. )

说明窗函数为文献窄时，STFT无频域的定位功能；(Note, when a narrow window function of literature, STFT-free frequency domain positioning function )

fft算法实现，通过matlab语言实现对fft算法的变成实现(solve fft)
