粒子群算法，实现最短路径规划

主要用于matlab中的一些基本方法的介绍 以一些功能简介，适合初学matlab用户(used for matlab)

描述了LTE下行物理信道的信道编码的详细实现，包括CRC校验、turbo编码、咬尾卷积编码和速率匹配等。(Describes LTE downlink physical channel channel coding detailed implementation, including the CRC check, turbo encoding, tail-biting convolutional coding and rate matching.)

New users and old of optimization in MATLAB will find useful tips and tricks in this document, as well as examples one can use as templates for their own problems. Use this tool by editing the file optimtips.m, then execute blocks of code in cell mode from the editor, or best, publish the file to HTML. Copy and paste also works of course. Some readers may find this tool valuable if only for the function pleas - a partitioned least squares solver based on lsqnonlin. This is a work in progress, as I fully expect to add new topics as I think of them or as suggestions are made. Suggestions for topics I ve missed are welcome, as are corrections of my probable numerous errors. The topics currently covered are listed below(New users and old of optimization in MATLAB will find useful tips and tricks in this document, as well as examples one can use as templates for their own problems.
