东大版数值分析上机题作业，包含牛顿迭代法、高斯赛德尔迭代法、龙格库塔法等(Southeast University version of 《numerical analysis 》homework ， including the Newton iterative method, high Sisaideer iterative method, Runge-Kutta method)

base_band.rar文件解压后可以在matlab平台直接编译运行，实现通信系统的升余弦基带 成型处理，码元速率，采样率、滚降系数都可以灵活设置，特别方便学习通信的同学加深对基带信号的理解。(base_band.rar unzip the files can directly compile and run matlab platform to achieve communication system raised cosine baseband shaping processing, chip rate, sample rate, roll-off factor can be set flexibly, in particular, to facilitate students to learn to communicate better to the base band signal understanding.)

一级倒立摆系统模糊控制的Matlab仿真程序，模糊控制器根据Matlab工具包里的slcp.fis修改。超调量很小(Matlab simulation program, an inverted pendulum system fuzzy control fuzzy controller based Matlab toolkit slcp.fis to modify. Overshoot is small)

说明：  RRT 的思想是快速扩张一群像树一样的路径以探索（填充）空间的大部分区域，伺机找到可行的路径。(The idea of RRT is to rapidly expand a group of tree-like paths to explore (fill) most areas of space, waiting for the opportunity to find feasible paths.)

论文设计第2部分,设定一个滤波器阶数,比较观察QMF(CQF OQF)在不同量化级下的误差,编码效率等(Thesis design, Part 2, set a filter order to compare observed QMF (CQF OQF) at different level of quantization error, coding efficiency)
