All five matlab file relate to the cluster structure of wireless sensor network. LEACH, BCDCP, ERP, HEED and so on are very helpful to do the simulation.

关于matlab的浙大课件包含word和ppt(ppt and word about matlab from zhejiang university)

说明：  二阶锁相环 matlab实现 QPSK BPSK(Implementation of QPSK BPSK with second-order PLL matlab)

说明：  心音QRS波检测算法，对于研究心音有帮助。(QRS wave detection algorithm for heart sound)

样条插值的相关matlab源码，包含6个.m的文件(Spline interpolation matlab source code, containing 6 m files)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )
