遗传算法实现优化函数，属于经典的遗传算法 (Genetic algorithm optimization function)

画出具有不同频率，相位的正弦信号及其DFT序列，并检验信号正交性(Draw different frequencies ,different phase of the sinusoidal signal ,and the DFT sequence, then check the signal orthogonality)

LDPC码的matlab实现，把解码的部分改过了，实验过很多次，符合理论要求，码长越长误码率越低(The implementation of LDPC code in MATLAB has changed the decoding part. It has been experimented many times and meets the theoretical requirements. The longer the code length, the lower the bit error rate.)

bpsk modulation in matlab

应用KNN算法解决0到9的手写数字识别问题，效果在90 以上，内部有两个数据集，一个为训练集（7291个数据），一个为测试数据（2791个数据），程序采用MATLAB编写，另附有文档，程序简洁易懂(Application KNN algorithm to solve 0-9 handwritten digit recognition problem, the effect is more than 90 , the inside has two data sets, one for the training set (7291 data), a test data (2791 data), the program written using MATLAB , attached a document, the program is simple and easy to understand)

可在MATLAB 5或MATLAB 6环境下运行，用于模式识别，人工智能领域。(In MATLAB 5 or MATLAB 6 environment running for pattern recognition, artificial intelligence.)

说明：  可以方便的计算混沌系统的李雅普诺诺夫指数，只要改变其动力方程即可。(Chaotic system can easily calculate the lyapunov exponent, as long as you change the power equation)

This Packages are dynamic Simulation Models for a doublePendulum and a robotic arm.

线性调频信号（chirp信号）的脉冲压缩处理的matlab程序例程。(Chirp signal (chirp signal) pulse compression processing matlab routine.)

说明：  模糊算子5种方法，应该有点用吧。能求出综合评价(There are 5 ways of using fuzzy operators. We can figure out the comprehensive evaluation)
