blitz++库的相应源码
Blitz++提供了一个N维(1—10)的Array类,这个Array类以reference counting技术实现,支持任意的存储序(row-major的C-style数组,column-major的Fortran-style数组),数组的切割(slicing),子数组的提取(subarray),灵活的Array相关表达式处理。另外提供了可以产生不同分布的随机数(F,Beta,Chi-Square,正态,均匀分布等)的类也是很有特色的。

As digital computers cannot generate true random numbers. So a pseudo random number generator must have uncorrelated sequences, long period, uniformity and efficiency.
‘myrand.m’ has pass the chi square test for uniform distribution.
