数字滤波器：数字信号处理及MATLAB实现(Digital Filter: Digital signal processing and MATLAB implementation)

说明：  在用matlab的时频分析中，不是所有信号的wvd都是可以，一些特殊的信号要用特殊的窗口来得到较好的效果(using Matlab in the time-frequency analysis, not all signals can be wvd, some special signal use special window to get good results)

this is a useful method of realizing prony in matlab system

主要是盲均衡的自适应算法，CMA算法，并且运用于均衡器之中。(Blind equalization of the adaptive algorithm, the CMA algorithm, and used in the equalizer.)

齿轮传动非线性分析，对扭转振动方程组进行求解，可得到齿轮扭转角随时间变化相关参数(Gear nonlinear analysis of torsional vibration equations are solved to obtain the twist angle of the gear change parameters over time)

说明：  有限元结构计算中，梁单元两节点（12自由度）的全局坐标系-局部坐标系转换(Global coordinate system to local coordinate system transformation of two nodes (12 degrees of freedom) of beam element in finite element structural calculation)
