using matlab to draw antenna beam pattern

采用多孔trous算法(undecimated wavelet transform)实现小波变换，用的是一维信号 (The use of porous trous algorithm (undecimated wavelet transform) the realization of wavelet transform, using a one-dimensional signal)

A DC/DC Boost Converter was developed using the simulink tool box

m序列生成和抽取，Gold码和kasami序列生成，三种序列子相关，互相性能分析等。程序完整，注释清楚，报告详细。(m sequence generation and extraction, Gold codes and kasami sequence generation, all three sub-sequences related to each other performance analysis. Program integrity, comments clear, the report detailed.)

这是希尔伯特--变换的MATLAB程序,希望对大家有用(hitbert matlab)

本书是《高质量c++编程指南》，林锐博士著，针对编程过程中可能会遇到的若干容易被忽略的问题进行了分析。(This book is "high-quality c++ Programming Guide" Dr. Lin Rui book for several problems easily overlooked programming process may encounter analyzed.)

说明：  可计算地下洞室的围岩稳定问题，模拟地下洞室的开挖、支护过程，介质可以是均质体，也可以是分区变化的非均质体，还可有夹层、节理等。(Calculate the stability of underground rock caverns, underground excavation simulation, supporting the process, the media can be a homogeneous body, you can also change the partition of non-homogeneous body, but also as a layer, joints and so on.)

关于polar 码的SC（Successive Cancellation）译码程序，与原作者用BP（belief propagation）实现的译码程序“Polar code encoder and decoder”可以对比看(This is a SC decoding program about polar codes)

说明：  matlab实现图像变化检测 分别用kmeans fcm flicm实现图像的变化检测(image change detetion by kmeans,fcm,flicm)

新的微粒群算法 利用matlab实现 简单(a new PSO)
