有关matlab较为基础的入门书籍。很适合初学者学习借鉴和使用。(For more matlab basic introductory books. It is suitable for beginners to learn and use.)

本文件是我们小组参加2013电工杯的数学建模比赛的文件，荣获全国2等奖！我们做的是电力系统分析的题目，内有基于matlab建立的三次平滑统计方法，以及神经网络智能算法，还有就是基于simulink的电力系统仿真程序！内附有程序说明文件。你一定能看懂的，不懂的可以留言给我！(This document is our electrician Cup 2013 team participated in the mathematical modeling of the game files, won the two prize! What we do is the subject of power system analysis, there are statistical methods based on cubic smoothing matlab established and intelligent neural network algorithm, there is a power system based on simulink simulation program! Enclosing a program documentation. You must be able to read and understand can leave a message to me!)
