选择不同的滤波方式：低通、高通、带通及带阻，进行频谱分析。(Select a different filtering method: low pass, high pass, band pass and band stop, spectral analysis.)

reverberation enhancement program

using servo characteristic equations,transfer function is derived by taking laplace

Matlab code for the Simulation of the Maxwell-Dirac and Schrodinger-Poisson systems

本程序主要用来在设计广义切比雪夫滤波器时，根据给定的指标要求能综合处其所需要的耦合矩阵的耦合系数，从而方便进行下一步的设计(This procedure is mainly used in the design of generalized Chebyshev filter can be integrated Department, they need the coupling matrix of the coupling coefficient, according to the target set by the requirements, in order to facilitate the design of the next)

三机九节点的matlab模型，，有需要的同学可以下载试用(IEEE9 model of matlab)

Linear Algebra - Math book

采用AHP方法，采用比较矩阵，对各层目标参数进行权重分配(AHP method using the target parameters weight distribution)

用于提取信号的时频域特征参数，比如信号均值、方差、以及一些无量纲的时域特征参数(Time-frequency domain characteristic parameters used to extract signals, such as signal mean, variance, and some dimensionless time domain characteristic parameters)
