说明：  LD算法，实现信号的分析，频谱分析，避免矩阵的求逆运算(failed to translate)

KALMAN filter for linear time invariant estimation

说明：  该算法连续系统的抗积分饱和的PID算法,用MATlab开发，能够管直接运行,可明显减弱几分饱和现象对系统稳定性的影响，当控制量与设定值偏差较大时，取消积分作用，以免积分作用过大引起系统的稳定性降低。(The algorithm of the anti-continuous system saturated PID integral algorithm, developed using Matlab and can directly run the tube can be significantly weakened somewhat saturated phenomenon on system stability, when the control volume and settings deviation is larger, integral role in the abolition of so as not to cause too large integral role in the stability of the system lower.)

数字调制技术的发展日新月异现如今信息技术不断的推陈出新，信息的传输及通信起着支撑作用。而对于信息的传输，数字通信已经成为重要的手段。因此，数字信号的调制就显得非常重要。数字调制是通信系统中最为重要的环节之一，而实现数字调制需要的方法就需要用键控法来实现，比如可以对载波的振幅、频率和相位进行键控。(ASK , FSK , PSK modulation and demodulation of the simulation comparison )

matlab的pde工具箱很薄弱，同时只能处理有限复杂度的问题，利用comsol强大的有限元分析与多物理场的耦合性，解决相当完美。 matlab与多物理场有限元软件的结合，本程序需要安装matlab7.0以上以及comsol multiphysics 3.0以上版本，建立客户端后可以方便的利用matlab控制有限元软件，进行建模计算。 本程序描述的是点电荷周围的电场以及电势。适合于初学者(The pde matlab toolbox is very weak, and can only handle a limited complexity of the problem, by using comsol powerful finite element analysis and multi-physical field coupling to solve quite perfect. matlab and multi-physics finite element software combination, the above procedure to install matlab7.0 and comsol multiphysics 3.0 or later, after establishing the client can easily control the use of matlab finite element software to model calculations. This procedure describes the electric field around a point charge and the electric potential. Suitable for beginners)
