一本数值分析英文书籍，各种方法均配有相应的程序，用matlab，fortran等编写，值得一看(A numerical analysis of the English books, various methods are equipped with the appropriate procedures, using matlab, fortran, etc., worth a visit)

三维时域有限差分程序，cpml吸收边界，介质表面采用网格均分技术(Three-dimensional finite-difference time-domain algorithm, CPML absorbing boundary, sharing media surface using grid technology)

在论坛上经常有朋友求关于信号上下包络的程序。 本程序为本人编写的一个matlab程序。(at the forum frequently for friends on the next signal envelope procedures. The procedures for the preparation of the one I Matlab procedures.)

拥有gui界面，实时描述三相配电网络情况（包括电压，电路损耗），由线损，三相荷载和无功补偿额为主要影响因素(With GUI interface, real-time network description of three-phase distribution (including voltage, circuit loss), by the loss, the three-phase load and reactive power compensation as the main factors)

无网格法权函数求解子程序，需要和以上载的第一个程序和用！(without grid power function for subroutines, and the need to contain the above procedures and the use of one!)

单径或多径瑞利衰落信道仿真，有较好的参考价值，主同步信号PSS在时域上的相关仿真，脉冲响应的相关分析算法并检验，基于kaiser窗的双谱线插值FFT谐波分析，重要参数的提取，结合PCA的尺度不变特征变换(SIFT)算法。( Single path or multipath Rayleigh fading channel simulation, There are good reference value, PSS primary synchronization signal in the time domain simulation related, Related impulse response analysis algorithm and inspection, Dual-line interpolation FFT harmonic analysis kaiser windows, Extract important parameters, Combined with PCA scale invariant feature transform (SIFT) algorithm.)
