声音识别程序，MATLAB程序，很好的例子，可以一看(Voice recognition program, MATLAB program, a good example, can one see)

This is a simple position location algorithm using Least Square Estimation algorithm. Timing information is time of flight (TOA) of signal between Tx and Rx. This code generally describes the Positioning method, Also it plots final coordinate of node in 2D. All other information was inlcuded as comments in source code.

小波分析及其应用的matlab程序，都是示列，对于学习利用matlab进行小波分析很有用(Matlab wavelet analysis and its application procedure are shown out, for learning using wavelet analysis is useful matlab)

MATLAB 矩阵运算的相关方法和说明。包含矩阵转置，矩阵加减乘除等等(MATLAB matrix processing code and description。)

Mur boundary 2D FDTD, 2维FDTD采取MUR二阶近似，时变动态电磁场(Mur boundary 2D FDTD， second order Mur approximation， time variant Time signal simulation)

Extended Kalman Filter MATLAB code

上传一个判断传递函数的稳定性的程序，当传函零极点位于虚轴右侧时系统不稳定，输出不稳定提示，系统稳定时输出稳定系统的传函。(Upload a function to determine the stability of the program transfer, the transfer function when the right side of the imaginary axis pole-zero when the system is unstable, unstable output prompt, the output transfer function to stabilize the system when the system is stable.)

本程序是现代谱导航分析中的惯性导航误差分析matlab程序，经过仿真验证，获得较为准确的结果。(The navigation program is modern spectral analysis of inertial navigation error analysis matlab program, through simulation, to obtain more accurate results.)
