说明：  simulink系统仿真：10kV 母线短路容量为10MVA，通过额定电压10/0.4kV，额定容量为100kVA，短路阻抗为5％的变压器与负荷相连， 阻感负荷RL 容量为50kVA，功率因数0.9。电力电子装置产生的5 次和7 次谐波电流均为5A；为了抑制7 次谐波在400V 母线处接入电容与变压器构成7 次滤波器。(simulink System Simulation: 10kV busbar short-circuit capacity of 10MVA, through the rated voltage 10/0.4kV, the rated capacity of 100kVA, short-circuit impedance of 5 of the transformer and load connected to sense the load resistance RL capacity 50kVA, power factor of 0.9. Generated by power electronic devices 5 and 7 harmonic currents are 5A to suppress harmonics in the 400V bus 7 access to capacitors and transformers constitute at 7 filter.)

这是一类特殊的椭圆偏微分方程Helmhotz方程。该程序是用迭代法求解Helmhotz方程的。(This is a special class of elliptic partial differential equations Helmhotz. The procedure is iterative method for solving equations Helmhotz.)

《数字信号处理教程——MATLAB释义与实现》的程序集，其中包括三部分。在examples子目录下本书全部例题的完整MATLAB程序；在subrtdsp子目录下是本书中自编的一些子程序，在运行例题程序时需要调用；这两个程序包是在学完本书后，读者能够读懂理解的。(dsk04 is a " digital signal processing tutorial- MATLAB Interpretation and Implementation" of the assembly, which consists of three parts. In all the examples subdirectory book example of a complete MATLAB programs in subrtdsp subdirectory is some self-compiled subroutines in the book, when running the example program need to call these two packages is in the completion of the book, the reader able to read to understand.)
