本工具包给出了数值分析这门课程中所涉及的所有问题所需程序。很不错(The kit gives the numerical analysis in this course all the issues involved in the necessary procedures. Very good)

fdtd matlab 2d simulation

用sobol方法计算基于方差的客观不确定性指标的程序。(Sobol method used to calculate the variance of uncertainty based on objective indicators of the program.)

能很好的帮助学习MATLAB，我自己正学习中(Can be very helpful in learning MATLAB, is the study of my own)

1、掌握MATLAB优化工具箱的基本用法，对不同算法进行初步分析、比较。 2、练习实际问题的非线性最小二乘拟合。(1.Understand the basic usage of Matlab optimization tool box. Analize and Compare different algorithms. 2. Practise nonliear minimum second order fitting using practical problems.)

基于SVPWM的三电平逆变的matlab仿真，DC-DC部分采用定功率单环控制，多抽样率信号处理，pwm整流器的建模仿真，实现串口的数据采集，进行波形数据分析。( Based on SVPWM three-level inverter matlab simulation, DC-DC power single-part set-loop control, Multirate signal processing, Modeling and simulation pwm rectifier Achieve serial data acquisition, Waveform data analysis.)

从MIDI文件中读取多基频，用于检测多基频的提取，是一个很好的方法，大家可以借鉴一下(MIDI multipitch )

说明：  间接法实现双谱分析，双谱是高阶谱分析的一种，matlab程序。(Bispectrum analysis by direct method)

matlab对EXCEL进行操作，包含xlswrite函数和xlsread函数。(matlab for EXCEL operation, including xlswrite functions and xlsread function.)

S-G滤波器，可实现较好的噪声滤除功能。(S-G filter which can achieve better in denoising stochastic noise.)
