One of the meschach features that simplifies writing the obvious stepping stone programs is a function that returns a random double in 0 , 1 Meschach有一个返回在[ 0 , 1 )之间的随机双精度数的函数,它是meschach的一个特色,可用于简化明显的踏脚石程序的编写。
Recall that both meschach and blitz have functions random number generators that deliver random doubles , and that cwmtx lacks native random generating capacity 如前所述, meschach和blitz有提供随机双精度数的函数(随机数生成器) ,而cwmtx自身没有产生随机数的功能。
Although meschach has a function that fills a matrix with 1 . 0s , it unfortunately lacks a function for filling a matrix with an arbitrary double or with random doubles 虽然meschach有一个用1 . 0填充矩阵的函数,但不幸的是,它没有用一个任意的双精度数填充矩阵的函数,也没有用随机双精度数填充矩阵的函数。
