这个是一个很详细的介绍了声学测量的内容和方法，是西工大的教学材料，希望对学习心理声学的同学有帮助。(This is a very detailed description of the acoustic measurement of the Neirong and the method is NPU teaching materials, Xi Wang students learning psychoacoustic help.)

this program for face recognizition

matlab的学习教程，里面含有很全面的介绍教程是ppt格式的，很容易理解，有利于初学matlab的同学的学习(matlab learning tutorial, which contains a very comprehensive introduction tutorial ppt format, it is easy to understand, is conducive to learning for students to learn matlab)

基于cpso文章，给出的一个matlab代码，添加测试函数即可运行。(Based on cpso, given a matlab code, add test function can be run.)

说明：  matlab中的Rayleigh信道模型，基于基于Clarke模型的Jakes仿真器(Rayleigh channel model in MATLAB, Jakes simulator based on Clarke model)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

利用各类插值的方法，对无线或者其他信道进行估计。插值包括2次、3次等(The use of various types of interpolation methods, or other wireless channel estimation. Interpolation of 2 times, 3 second-class)

用MATLAB进行探索数据分析，理论和应用同时介绍，并在书中列出不少MATLAB实现的例子(Exploratory Data Analysis with MATLAB, introduce exploratory data analysis methods and algorithms)

说明：  Any change to the value of Mresults in immediate and phase-continuous changes in the output frequency

包含优化类的几个简单示例程序，合成孔径雷达（SAR)目标成像仿真，主要是基于mtlab的程序，计算加权加速度,包括面积、周长、矩形度、伸长度，D-S证据理论数据融合。( Optimization class contains several simple sample programs, Synthetic Aperture Radar (SAR) imaging simulation target, Mainly based on the mtlab procedures, Weighted acceleration, Including the area, perimeter, rectangular, elongation, D-S evidence theory data fusion.)
