说明：  ofdm调制，仿真以及系统的性能的分析，估计系统的误码率(ofdm modulation, simulation and analysis of system performance, the BER is estimated)

说明：  这份资料是关于MATLAB的初级介绍，对于初学者非常实用，如果想快速学会使用matlab,建议大家先看看这份资料。谢谢！(This information is on the MATLAB primary introduction is very useful for beginners, if you want to quickly learn how to use matlab, suggest that you take a look at this information. Thank you!)

Lamb波群速度，相速度，波长随着频率的变化(Lamb wave scpoe)

In order to capture the spatial dependence of gray-level values which contribute to the perception of texture, a 2d dependence matrix known as a gray-level co-occurrence matrix is extensively used in texture analysis.So, this is a code that calculate a co-occurrence matrix of the image and return the following features: ENERGY, CONTRAST, CORRELATION and HOMOGENEITY.

对某个三维集合体进行matlab重积分计算(Double integral calculation )

这是一个非常有用的程序主要是用来光谱降维处理的手段有PCA,LCA,LLE,Isomap等(This is a very useful procedure mainly used for spectral dimension reduction processing by means of PCA, LCA, LLE, Isomap, etc.)

the day of year是指这一年已经逝去的天数（包括当天） 。在平年中，它的取值范围为 1 到 365，在闰年中，它的取值范围 1到 366。编写一个 MATLAB 程序，输入年，月，日， 输入为对应的 the of year。 (the day of year is the year the number of days have been lost (including the day). In the average year, it ranges from 1 to 365, in a leap year, it ranges from 1 to 366. Write a MATLAB program, enter the year, month, day, enter the corresponding the of year.)
