提供两个函数，通过均匀分布函数来生成正态分布随机数。-Provides two functions, the uniform distribution function to generate normal random numbers.

拉丁超立方抽样，调用方式如下：S=lhs(m,dist,mu,sigma,lowb,upb) m: a scalar,the number of sample points dist: A row with distribution type flags of basic random variables the value of the flag can be 1 (for uniform distribution, 2(for normal distribution), 3
