说明：  用图表表示出语音信号的语音信号时域波形，短时幅值和短时过零率，短时能量和短时过零率，短时幅值和短时能量，短时能量和短时幅值--hamming window。(Graphically show the voice signal voice signal waveform, amplitude and short-zero short-term rates, short-time energy and short-term zero crossing rate, short-term amplitude and short-term energy, short-term and short-term rate of energy value- hamming window.)

用matlab仿真一维和二维自适应波束形成(DBF)(simulate one and two-dimension DBF)

计算单模光纤的色散曲线，最后拟合出色散随波长变化的曲线(Single-mode fiber dispersion curve calculation, the final fitting with excellent wavelength dispersion curve)

说明：  M AT L A B有一些命令可以来控制M AT L A B语句的执行，如条件语句、循环语句和支持用 户交互的命令，本章将介绍这些命令.(M AT LAB some commands to control the implementation of M AT LAB statements, such as conditional statements, loop statements, and support the use of Users interact with the command, this chapter will describe these commands)

基于三电平逆变器的有源滤波装置设计，仿真模型完整，运行调试成功。(Based on the design of the active filter device of the three-level inverter, the simulation model is complete and the operation and debugging are successful.)

自己搭建的三电平二极管钳位式有源滤波器，采用双闭环控制方法，利用SVPWM作为触发脉冲(Built their own three-level diode clamp active filter, the use of double closed-loop control method, the use of SVPWM as a trigger pulse)

计算数独的好方法，能够快速解决问题，使用方便(Good way to calculate the number of independent, able to quickly solve the problem, easy to use)

This is a pdf filw of the course Nonlinear Programming in MIT

it s about numerical analysis method using matlab or microsoft excel program.
