matlab实习卷积运算。很高兴与大家分享此代码。(Matlab internship convolution operators. Very pleased to share with you that this code.)

此文件介绍了matlab的基础知识，适合于初学者进行学习，希望对大家有所帮助(This document describes the basics of matlab, suitable for beginners to learn, we want to help)

图像相似判断matlab用于两个图片的相似度进行比较和分析，一个采用巴氏系数计算法。另外一个rfg越接近1则越相似(matlab similar )

一个实用的傅里叶分解程序,程序可以输出源曲线和频谱图(a fourier analysis function, which outputs the orgrinal curve and frequncy map of components)

我们设计和实验证明 布拉格光栅波分复用器 三波长的平面光波电路复用 公交车站台。1310和1550 nm的光，被设计成 由一个半周期通过定向耦合器分离后 和一个完整的周期耦合作用与0.07和0.19分贝的损失， 分别。1492 nm的光反射回来的布拉格 光栅对定向耦合器及其制作少损失 超过2分贝。我们也介绍和讨论新概念 集成光学三工收发器，使用此过滤器。 (We designed and experimentally demonstrated a Bragg grating-assisted wavelength-division-multiplexing filter for the three-wavelength multiplexing on a planar-lightwave-circuit platform. The 1310- and 1550-nm lights were designed to be separated after passing the directional coupler by a half-cycle and a full-cycle coupling actions with losses of 0.07 and 0.19 dB, respectively. The 1492-nm light was reflected back by a Bragg grating fabricated on the directional coupler and its loss was less than 2.0 dB. We also introduced and discussed the new concept of an integrated optical triplexer transceiver using this filter.)
