基于紧格式线性化方法与偏格式线性化方法，可将非线性系统线性化，后用PID控制，设计控制器(Based on tight format linearization method and partial format linearization method, nonlinear system can be linear, with PID control, to design the controller )

This toolbox is designed for researchers in Computational Intelligence as well as application developers, students, and classroom labs. It is robust enough that several papers have been developed using it but it

LBM Lattice Boltzmann格子波尔兹曼matlab程序，二维的，初学者适用(LBM Lattice Boltzmann Lattice Boltzmann matlab program, two-dimensional, beginners applicable)

该程序能够对得到的重力场数据进行垂向求导，对于重力数据处理很有用。(The program can be on the gravity field data were obtained for the vertical derivative of gravity data processing, very useful.)

matlab simulink主要介绍了simulink模块的使用，适合初学者学习！(matlab simulink simulink module introduces the use of, suitable for beginners to learn!)

用于参数估计的极大似然估计法,简单，适用，方便(Maximum Likelihood method for parameter estimation，Simple, convenient, applicable)

能很好的计算李雅普诺夫指数，对初学这有一定的帮助Lyapunov+Exponents+Toolbox.rar(Well the calculation of the Lyapunov exponent, for beginners this will certainly help. )

Retinopathy detection

1. 给一段原始的语音信号（可以是自己录制的一段语音），加上一频率为3.8kHz的高频余弦噪声和频率为3.6kHz的高频正弦噪声（幅度自己可以选择），用窗函数设计一滤波器（要求最小阻带衰减为50dB）对加噪后的语音信号进行滤波，画出滤波器的频率响应曲线，画出滤波前后的时域图和频谱图。 需要用到的函数： fir1 用窗函数设计FIR滤波器的函数 2. 用GUI设计一界面（如图1所示）完成如下功能： 1） 输入一语音信号，画出语音信号的时域图和频谱图； 2） 对语音信号加噪处理，画出加噪后的时域图和频谱图； 3） 给定滤波器的性能指标，采用几种不同的方法设计滤波器对加噪信后进行滤波，画出各滤波器的频率响应曲线，画出滤波后的时域图和频谱图。 (1. to some of the original speech signal (which can be a voice you record yourself), plus a cosine frequency of 3.8kHz frequency noise and frequency of 3.6kHz frequency sinusoidal noise (in the range that they can choose), with a window function to design a filter (requires a minimum stop band attenuation is 50dB) after adding noise to the speech signal is filtered, the filter frequency response curve to draw, draw diagrams and time-domain spectrum before and after filtering. Need to use the function: function fir1 with window function design FIR filter design 2. Using a GUI interface (Figure 1) complete the following functions: 1) an input speech signal, the speech signal in the time domain to draw graphs and spectrum 2) adding noise to the speech signal processing, draw diagrams and time-domain plus noise spectrum after 3) to set the filter performance, using several different methods designed to filter letter after adding noise filtering, draw the frequency response curve of each )
