说明：  在MATLAB里开发的几个常用的图像处理工具，简单易用，初学者可以试试。(matlab image process easy )

The NAVSTAR GPS (NAVigation Satelllite Timing And Ranging Global Positioning System) is an all-weather, space-based navigation system developed by the U.S. Department of Defense to determine ones position, velocity, and time accurately in a common reference system on the Earth. The present constellation consists of nominally 24 satellites and provides global coverage with four to eight satellites simultaneously observed above 15 ? elevation.

计算光子二维晶体米卡良透镜折射率分布的程序，同时给出米卡良透镜在径向的晶体柱半径分布(Calculated two-dimensional photonic crystal lens refractive index distribution of Mika good program, and gives good Mika crystalline lens in the radial distribution of column radius)

说明：  BD块对角化算法研究，MIMO算法研究，MIMO线性预编码(Research on BD block diagonalization algorithm)

A few examples of designing and implementing fir filters with Matlab-filtering a signal taken from the mic input of the soundcard and putting it on the headphones output chanel and removing noise from ECG.I m uploading this file just because I need to register to see another file and I haven t translated it in English but the code is understandable. If someone is interested e-mail me.

西北工大《声学基础教案》1－3，很不错哦 西北工大《声学基础教案》1－3，很不错哦(West Completion "acoustic based lesson plans," 1-3. Oh, very good West Completion "acoustic based lesson plans," 1-3, oh very good)

说明：  噪声的加入小实验。用以实现 加入噪声的功能，从而发现，加入噪声的方法与表现。(MATLAB realase an input noise,and to make the photo become a nomal looking photo.)
