说明：  多维随机数的生成方法，一维随机数生成方法，高维随机数的生成方法(Generation methods of multidimensional random number, one-dimensional random number and high-dimensional random number)

最好的dijkstra 算法 matlab实现。 可以计算任意两点间的最短距离和路径。 不要参考其他的matlab程序，他们的路径都有问题。(Best Dijkstra algorithm matlab. You can calculate the shortest distance between any two points and path. Do not refer to other matlab program, their path has a problem.)

可以实现十几位整数的四则运算，效率也较好(Four operations can be more than a dozen integer,and the efficiency is better)

说明：  克里金、反距离插值算法_栅格图等值线填充等(Kriging, inverse distance interpolation algorithm _ isogram filled grid map, etc.)
