说明：  floy 算法实现寻找最短路径问题,类似的还有迪克斯屈拉算法(floy algorithm to find the shortest path problem, there is a similar pull algorithm Dix ​ ​ Qu)

一个简单的遗传算法算例，可以帮助初学者理解一下遗传算法(A simple genetic algorithm example, can help beginners to understand the genetic algorithm)

说明：  1.同时对多个光谱数据进行一阶导数计算，并保存在元胞数组中。2.对光谱数据进行取均值，每三个列为一组。(At the same time, the first derivative of multi-spectral data is calculated and stored in the cell array.The spectral data are averaged and divided into three groups.)

用matlab实现的boosts开关变换器的仿真图，一共四幅图，对于学习非线性电路的同学有用(Matlab achieved by switching converter boosts the simulation map, a total of four maps, non-linear circuit for the students to learn useful)

merge closest floating values with a step

ACF(x) plots the sample autocorrelation function of the univariate time series in vector x. By default, the sample autocorrelation function is plotted up to lag 25. ACF(x,k) plots the sample autocorrelation function up to lag k. ACF(X,k, name ) sets the title of the plot to name .

hartley计算机视觉中，利用对极几何和极线原理，求取图像之间的匹配，实现摄像机自标定，里面有对应的pdf文件原理说明(Hartley s Computer Vision in the multi-view geometry program, contact the three-dimensional reconstruction of the pole geometry and take pole lines, and camera self-calibration, which has a corresponding program and pdf files)

用MATLAB计算二值图像的最小外接矩形，并输出矩形范围。(Calculating the minimum circumscribed rectangle of two valued images)

A matlab function that calculates the inverse short term Fourier transform with adjustable parameters.
