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!)

辛普森公式的自适应积分：在整个积分区间使用相同的小步长 ，以保持整体精度。然而，实际应用中，函数的振荡起伏的情况处处不同，这并没有考虑到曲线的某些部分变化剧烈，需要比其他部分多加考虑的情况。而有些部分，曲线的变化缓和，因此可以采用大于平均值的步长 来进行积分。因此，引入一种能够在函数值变化大的区间采用小步长的方法是很有用的。这种方法，称为自适应积分。(Adapt integral based on Simpson integral)

论文使用一种经典的特征提取方法—主成分分析法（PCA）进行特征提取，其基本思想是降维。降维后的数据除了计算工作量减少之外不会减少原始数据所包含的有效信息量。(This paper use a classical method for feature extraction—Principal Component Analysis(PCA)with the basic idea of dimensionality reduction(it still contains all valid information).)

对经典协议LEACH的改进版本，可以出图3个，对初学很有帮助，大家有兴趣的可以看看。(LEACH agreement on an improved version of the classic, you can plot three, very helpful for beginners, we are interested can look at.)

一个基于matlab实现的计时器源码，供大家学习。(A matlab implementation of the timer source for everyone to learn. )

研制了一套基于pulse多分析仪的声级计自动检定测试系统，主要介绍了系统的工作原理，实现方法及应用(the automatic measurement system of sound level meter is carried out,this system is built on the pulse multi-analyzer)

用matlab实现单双枝节阻抗匹配，并用smith圆图匹配演示过程(Using matlab to achieve single-and double-side impedance matching, and demonstrate smith circle graph matching process)

object removal在图像处理中的意思是用户可以随意擦去图像中的一个物体，算法可以自动的用背景中的信息补去空洞，达到看不出来是处理过的效果，又叫inpainting，该程序由matlab写成，效果非常好，文档、演示、测试图像均齐全(object removal in image processing means that users can remove images of an object, the algorithm can automatically use the background information to fill empty, reaching out is not to look over the effectiveness of treatment, also known as inpainting, the program by matlab languages, has very good results, documents, presentations, test images have complete)
