用matlab语言编写的最小生成树kruskal算法的通用源程序 。(Using matlab language Kruskal minimum spanning tree algorithm for general-purpose source.)

Min/Max filter，最大最小滤波器，说明看英文，只是国外的人写的代码， (Description The filter computes the minima and/or maxima of an array over sliding window with a given size. Multidimensional array is fully supported: running filter in 1D, 2D filter for image processing applications (erosion/dilatation), 3D and more. This package has been implemented with a special care on the running speed: the MEX engine uses an algorithms that requires no more than three (3) comparisons per element and per dimension in all configurations. All numerical and logical class arrays are supported. Contributor (beside author) is Vaclav Potesil Acknowledgements This submission has inspired the following: Free-knot spline approximation MATLAB release MATLAB 7.8 (R2009a) Other requirements MEX correctly setup NO image processing is required Download a tiff file for )
