MATLAB数字图像处理灰度均匀化gray uniformization(gray uniformization)

平面8节点单元类，可以输出单元的刚度，并可通过形函数插值得到内部各点得位移、应力等。对各位以前编写的程序的一个补充和完善吧。(plane eight-unit category, the output unit stiffness, through the shape function can be interpolation points in the internal displacement and stress. Right before you and the procedure for the preparation of a supplement and perfect it.)

说明：  MATLAB 前推回代法的配电网的潮流计算程序，适合于辐射性配电网和少环的配电网(MATLAB forward and backward substitution method of distribution network load flow calculation program, suitable for distribution network and less radiation distribution network ring)

程序是基于matlab的AWGN程序。16PSK(Matlab program is based on the AWGN process. 16PSK)

A programmable-logic controller (PLC) is a compact computer-based electronic system that uses digital or analog input/output modules to control machines, processes, and other control modules. A PLC is able to receive (input) and transmit (output) various types of electrical and electronic signals and use them to control and monitor practically any kind of mechanical and/or electrical system.

说明：  ：文章分析了轻型高压直流输电的基本原理，通过采用定直流电压、定交流电压的控制方式，建立了基于MATLAB的轻型直流输电系统的仿真模型，并以一个单机系统为例，分析了系统的控制模型。通过对三相 接地短路的分析，验证了所建立的仿真模型和控制系统的正确性和合理性，为进一步研究轻型直流输电系统的物理模型奠定了理论基础。(M ATLAB sim ulation of HVDC light system)
