如何在MATLAB中为随机数生成器设置统一的种子? [英] How to set a unified seed for random number generators in MATLAB?

问题描述

我正在编写代码并使用MATLAB中的现有函数.如果这些函数使用随机数生成器怎么办.有没有一种方法可以固定这些函数的种子而无需更改它们的代码? MATLAB中是否有执行此操作的命令?

I'm writing code and using existing functions from MATLAB. What if these functions use random number generators. Is there a way I can fix the seed of these functions without having to change their code ? Is there a command in MATLAB that does this ?

推荐答案

通常，代码将使用Matlab的内置随机数生成器.您可以使用以下内容对其进行播种:

Normally code would use Matlab's built-in random number generator. You can seed it with the following:

rng         = RandStream.getDefaultStream;
rng.reset(your_seed_value_here);

一个人也可以创建RandStream对象并使用它们(从而避免使用默认流)，但这在大多数情况下都应该起作用.

One could also create RandStream objects and use them (thereby avoiding the default stream), but this should work most of the time.
