SkewT分布是近年来得到广泛使用的一种参数化分布。区别于传统的正太分布、学生-t分布，SkewT分布除了具有厚伟特征之外，还引入了偏斜特征。该分布对于金融领域的研究与应用具有十分重要的价值。当然，也是一个重要的统计工具。SkewT分布由Bruce E. Hansen(1994)构造，本源码包括SkewT分布的密度函数、累计概率、随机数生成、理论矩。(SkewT distribution has been widely used recently. Different from traditional Normality and Student-t distribution, SkewT parameterizes both tail-thickness and skewness. SkewT is valuable to financial applications and studies, and other statistic tool. SkewT is firstly introduced by Bruce E. Hansen(1994). This package includes M files on the density of SkewT, CDF, random number generator and theoretical moments of SkewT.)

该程序为机器人最优路径的Matlab源程序，并且基于方向优先权的机器人最优路径寻找算法，也可用于求解迷宫的最短路径，算法中是以100*100的格点为实例的，其中标0的位置为可行的点，标1的为障碍物，参考者可以根据自己的情况修改场地信息矩阵和起始点、目标点中间的算法不用修改。 (Robot optimal path Matlab source code of this program is based on the priority direction of the robot to find the optimal path algorithm can also be used to solve the maze of the shortest path algorithm is 100* 100 grid points as an example, where standard 0 position for the possible points, S 1 for the barrier, the reference can change according to their own circumstances and venue information matrix starting point, target the middle of the algorithm do not change)
