matlab学习资料，对于初学者来说是一本不错的入门教程(matlab learning materials, for beginners is a good introductory tutorial)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

Image Edge Extraction Algorithm Calculation of Lagrange and Newton

说明：  am调制解调，水平有限，希望大家多多指正(am modulation and demodulation, the level is limited, a lot of hope that we can correct me)

This is the code of DEEC protocol of wireless sensor network. It is a matlab code

说明：  计算长方形产生的重力异常,理论计算和具体的实现方法.(Calculation of gravity anomaly caused by rectangle)

energy efficiency computation when wireless body area sensor node communicates to the coordinator through wireless link in the presence of a relay node when the distance is varied

this program simulates 2D electromagnetic Maxwell equations , by using finite difference time domain method FDTD..and it simulates the perfect matched layer to prevent the reflections that may occure at the boundaries of the problem space

这是一个matlab的工具箱，里面有很多常用的例程，对于matlab的学习有很大的帮助。(This is a matlab toolbox, there are many common routines for matlab learning a great help.)
