Gradient code. Use this to do gradient of image.

最小均方误差信道估计LS_MSE_calc.m仿真程序。用于ofdm信道估计。(Simulation of main channel LS_MSE. You wish to be useful.I hope that they will bring convenience to. If there is a need to contact.I wish good!)

说明：  matlab的应用，我搜集来的，对学matlab挺有用的。(matlab application, I come to collect, to learn matlab Tingyou use.)

S-function is a powerful customized function that fits into the matlab environment.(This pdf contains instructions for build your own s-function.)

在VC++ 集成环境里，若想实现与MATLAB引擎之间的通讯，应该对VC++进行一些设置(In VC++ Integrated environment, wants to achieve with the communication between the MATLAB engine, there should be VC++ Some settings)

计算电磁学中FDTD（有限时域差分法）二维的算法程序。(FDTD (finite difference time domain method) two-dimensional algorithm program in computational electromagnetics.)

to find the extremas of any 1-d signal

该程序用于读取GTOPO30. GTOPO30 是一个全球的数字高程模型，它覆盖西经180度至东经180度，南纬90至北纬90度的所有区域。它的分辨率为30秒（即0.00833333度），生成 一个21,600（行）×43,200（列）的DEM。其高程值范围在-407至8752米。在数字高程模型中，海洋地区被指定为-9999 。 低地沿海一带，海拔至少有1米。(GTOPO30 is a digital elevation model for the world, developed by USGS. It has a 30-arc second resolution (approximately 1 km) and is split into 33 tiles stored in the USGS DEM file format.)

说明：  异步电机的SVPWM闭环的DTCsimulink文件，可以闭环正常运行，波形还行(Asynchronous motor SVPWM closed-loop dtcsimulink file, can be closed-loop normal operation, waveform is OK)

同步在数字接收机的解调中非常重要，本程序详细描述了用平方定时算法描述的符号同步算法，(Time square Algorithm Symbol synchronization )
