科学计算器的matlab程序，完整可运行 包括程序和界面( 自动检测语言 划词 双语对照 中文 » 英语<~复制 Scientific calculator matlab procedures, including complete run programs and interfaces )

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)

说明：  k近邻 (k nearest neighbor)

k-means，经典聚类算法DBSCAN的MATLAB实现，简单易懂，可以运行(k-means，Classical clustering algorithm concentration of MATLAB implementation, easy to understand, you can run)

这是MATLAB中文帮助文档,对大家学习这个语言的帮助很大,非常方便实用.(This is the MATLAB Chinese help files, for all of us to learn this language is very helpful, very convenient and practical.)

This a one dimensional level set code where the interface grows with normal speed equal to one. The code generates a movie showing the interface motion and the evolution of the level set function.

自己写的相关性检测和线性预测编码的小程序，可以作为初学者的参考(Write their own correlation detection and the linear predictive coding of small procedures, can be used as a beginner s reference )

说明：  1/3倍频程分析。有需要做这方面研究的同志们可以好好看一下。(1/3 octave analysis. There is a need to do research in this area can be a good look comrades.)

振动理论中四阶龙格库塔法解决单自由度振动问题，希望对大家有帮助(Vibration Theory fourth-order Runge-Kutta method to solve the problem of a single degree of freedom vibration)

例子关于buck的仿真，里面有simulink文件和一个绘制buck输出功率与占空比关系的matlab源文件。(About buck simulation example, which has drawn buck simulink file and a relationship between output power and duty cycle of the matlab source files.)
