Introduction

Yale人脸数据库B扩展库（mat 格式）ExtendYaleB数据库，可以作为人脸分类分割实验数据(Yale face database B extension library (mat format) ExtendYaleB database can be used as face classification division of experimental data)

说明：  《Matlab从入门到精通》所有的源程序。(《Matlab from entry to the master》 all of the source.)

对一段振动信号emd分解后，求每个分量的峭度值，选取峭度最大的分量，求其包络谱，能够明显看出特征频率。(After a period of vibration signal emd decomposition, seeking kurtosis value of each component, the largest component of kurtosis, seeking its envelope spectrum, can obviously see that the characteristic frequency.)

说明：  经典的UPML边界程序，用于电磁仿真，使用的是高斯脉冲(The classic UPML border procedures for the electromagnetic simulation, using a Gaussian pulse)

matlab 地震反应可以算出简单层状剪切结构的地震响应，该程序为线性的(matlab seismic response can calculate the seismic response of a simple layered shear, the program is linear)

海面上一轮船沿直线匀速前行，速度为30公里/小时，船上有一雷达可用来测距、测角，船长关心的是周围目标那些是活动的船，那些是不动的岩石，若是活动的船，请按下面假设，分析有关因素，给出船的运动方向和速度。(ships on the sea along a straight uniform before the trip and a speed of 30 km/hour, On board there is a radar can be used to measure the distance and angle measurement, the captain of concern is around the goal of those activities is the boat. those are immobile rocks, if the ship by the following assumptions, analysis of the relevant factors, the boat is the direction and speed of movement.)

根据P. Luukka, (2011)的文章编写的特定提取的方法，使用了相似性测量和模糊测量(According to P. Luukka, specific extraction method (2011) article written using a similarity measure and fuzzy measure)
