本文章详细介绍了PLSR片最小二乘回归的原理，以及如何用matlab源代码实现PLSR建立回归模型，以及交叉检验，得到最优模型。(This article describes in detail the principle of least squares regression PLSR piece, and how to use matlab source code PLSR regression model, and cross-examination, the optimal model.)

MATLAB作为通讯控制类极好的仿真软件平台，而这是通过其开发的各种控制方法的具体应用，非常好使。(MATLAB as a communications control class excellent simulation software platform, which is through its development of various control methods specific applications, so very much.)

运用粒子群和改进粒子群算法求解典型函数 具有可视化的功能(And improve the use of particle swarm particle swarm algorithm with a typical function of visual function)

无参考的图像质量评价算法，基于图像的空域与频域的信息熵，超过现存的所有质量评价算法。(No reference image quality uation algorithm, and information based on spatial frequency domain of the image entropy over all existing quality uation algorithm.)

说明：  互相关法的实现。一般多用于图像配准之中，能够求两幅具有角度偏移图像的互相关值大小。互相关值能够应用于众多方面。(Implementation of Cross Correlation Method. Generally used for image registration, can be obtained with two angle offset image cross-correlation value size. The cross-correlation value can be applied to a number of aspects.)

说明：  四旋翼无人机，模糊控制（matlab，simulink仿真）(Four-rotor UAV, fuzzy control (matlab, simulink simulation))

双通道星载合成孔径雷达（DPCA），第一个天线发射信号，两个天线同时接收信号。(Dual-channel satellite synthetic aperture radar (DPCA), the first launch of an antenna signal to two antennas to receive signals at the same time.)

该文件是一个详细分析PID控制的文件。通过示波器，改变参数下，可以很形象的观察输出波形的变化，这样可以更加直观的学习PID控制，加深对它的理解(The file is a detailed analysis of PID control file. Through the oscilloscope, change the parameters, can be very image of the observed output waveform change, so that we can more intuitive learning PID control, deepen the understanding of it )

均值滤波和中值的matlab代码，很有用,比较适合初学者使用。。(meanfilter and medianfilter，pretty good!!)
