Numerical solution of 1D wave equation in finite differences (matlab code)

水平集经典方法的matlab工具箱,可以省却大量精力。(level set by the classical method of Matlab toolbox, we can save a great deal of energy.)

说明：  调用normfit函数求正态总体参数的最大似然估计和置信区间(Normfit function calls seeking normal population parameters of maximum likelihood estimates and confidence intervals)

封装好的模块是PV（光伏电池），本例利用斜坡信号作为电压端输入，仿真出光伏电池的外特性。(The packaged module PV (photovoltaic cells), in this case the use of the ramp signal as the input voltage terminal, simulation of the external characteristics of the photovoltaic cells.)

说明：  数学建模中的程序编写，矢量数据的显示，达到建模过程中用户的需求(Programming in the mathematical modeling and display of vector data, to the needs of users in the modeling process)

This a platform to design a data base schem.

这是一个MATLAB程序，关于正态云模型的期望曲线的程序。(This is a MATLAB program, the expectation of normal cloud model curve of the program.)

Matlab 语言编写的用于彩色分割，边缘检测，基于区域生长的图像分割(Matlab color segmentation，edge detection，region growing image segmentation.)

基于自建数据库的音乐识别及检索软件 ； 利用Matlab开发软件, 通过抓取录入歌曲的音高(pitch tracking)绘出声音的频率变化并进行降噪和润滑（smoothing）处理 与数据库中歌曲的频率变化图比对，计算出相似度top10的歌曲并显示。 (Based on self-built of music recognition and retrieval software developed using Matlab software, change the pitch of a song by crawling entry (pitch tracking) plots the frequency of the sound and noise reduction and lubrication (smoothing) processing Frequency changes in the diagram songs than calculate the similarity top10 songs and displayed.)
