FDTD Finite-Difference Time-domain in free space no ABC FDTD(t) runs FDTD for time t. FDTD implements the FDTD/staggered leapfrog scheme over time 0-max_time and space 0-max_space. This program simulates a gaussian pulse in the grid specified with max_time and max_space. The pulse is sent from the center of the problem space and disperses in both directions -Kira Heater

感知器的MATLAB实现，现在很好的啊，请大家(Perceptron MATLAB realized, ah good now, please)

研究信道译码，测试程序，为保障有效运行，请注意安装环境软件的版本正确与否(study for channel decoding)

获得图像局部增强时，每个象素的指数增强系数，指数增强系数有原图像中的灰度值与其周边象素比较获得([Coeff_en_local, lum_mask]=enhance_coeff_local_bilateral(lum_ori,window_r,sigmad,sigmar))

说明：  基本的Qpsk调制和解调方式，采用的是A方式，并且画出误码率和信噪比的比例图(QPSK simulation)

使用matlab编写的信道估计与误码率测试程序，可以作为OFDM学习的参考,(Prepared using matlab channel estimation and bit error rate testing procedures, can be used as a reference OFDM learning,)

绘制单颗卫星、单架飞机的时延多普勒图形。(Plot DelayDoppler of single target.)

一LSB的数字水印代码，很好用，代码里面有注释说明(a digital watermark code is useful, code inside annotated)

matlab源代码，实现红外图像的非均匀性校正，代码经试验无错误(Infrared image non-uniformity correction)

说明：  基于matlab的私家电动汽车日负荷曲线例程可，可在此基础上更改相关数据。(Based on the matlab routines can be private electric cars daily load curve, can be modified on the basis of the data.)
