matlab数据处理小程序

hand image pre-processing first stage denoise

说明：  该程序包是美国某大学的团队联合编写的潮流计算程序，包含高司法、牛拉法、PQ法等，对电力系统的潮流计算描述的非常完善。(The package is a university in the United States jointly prepared the team flow calculation program, including high-judicial, cattle Rafah, PQ law, the power flow calculation is described very well.)

The ouput is the TE/TM band structure (first five bands) along pricipal directions (G-X-M-G) of a square-lattice photonic crystal with unit cell consisting of a substrate of "epb" relative permittivity with circular rods(holes) of "epa" relative permittivity and radius "r". Usage is SharifPWE_BZplot(N,RES,r,epa,epb) N: N in PWE algorithm (number at which the summations are truncated) RES: number of the divisions on every side of BZ#1 r: normalized radius of the circle of holes/rods (0<r<0.5) epa: relative permittivity of holes/rods epb: relative permittivity of the substrate Written by Amir Hosseini for the Course Photonic Crystals (C) Copyright 2005 School of Electrical Engineering Sharif University of Technology All Rights Reserved
