There are many options to choose from in the<random>header, and any of them is preferable to the outdated C Runtime functionrand(). For information about what's wrong withrand()and how<random>addresses these shortcomings, seethis video. ...
l假如Seed for Random function不为空,为手动输入的某个固定常量, 1) Per Thread(User)? 设置为True,那么每个线程都使用自己的随机数生成器,因为Seed相同,所以,每次运行脚本,每个线程获取到的随机数变量值是一样的。 2) Per Thread(User)? 设置为False,那么每个线程共享同一个随机数生成器,所以,每次运行脚本,...

If you specify distribution parametersA,B,C, orD, then each element inRis the random number generated from the distribution specified by the corresponding elements inA,B,C, andD. Alternative Functionality randomis a generic function that accepts either a distribution by its namenameor a probability...
When generating random real numbers, therandnfunction generates data that follows the standard normal distribution: f(x)=1√2πe−x2/2. Here,xis a random real variable with mean 0 and variance 1. When generating random complex numbers, such as when using the commandrandn(...,like=1i)...
