用有限元方法求解Helmholtz方程，可以自动划分生成网格，解有图像显示(Using the finite element method for solving Helmholtz equation, can be automatically generated into the grid, have image display solution)

控制系统计算机辅助设计——MATLAB语言与应用(第2版)一书的源码(Control System Computer Aided Design- MATLAB Language and Applications (2nd Edition))

说明：  智能天线中的波束成型算法，系统仿真程序，matlab代码(Smart Antenna beamforming algorithm, the system simulation program, matlab code)

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)

some of the important matlab codes for calculating PSD of a signal for students

说明：  Power Spectral Subtraction (SS) for speech enhancement Storing original signal to compute PESQ & SSNR measurment Noise magnitude calculations - assuming that the first 5 frames is noise/silence

说明：  关于滤波器的源码 能够在MATLAB上运行(On the source filter can be run in MATLAB)

matlab 基础上通过最小二乘法进行模态参数识别，得出固有频率，振型，阻尼比，图形(by the least squares method matlab based on the identification of modal parameters obtained natural frequency, mode shape, damping ratio, graphics)

用MFC对话框做的ofdm系统的仿真程序，很形象，比较适合ofdm的初学者(To do with MFC dialog ofdm system simulation program, it is the image more suitable for beginners ofdm)
