如何从特定的用户定义范围生成随机向量? [英] How to generate random vector from specific user defined range?

问题描述

我想生成包含用户定义范围内的数字的随机向量.例如: 数字= [1 2 4 10] 随机向量应始终由这些数字组成.例如. rand_num = [1 1 2 10 5 2 10] 谢谢.

I want to generate the random vector containing the number from the user defined range. For example: numbers = [1 2 4 10] The random vector should always consist of these numbers. Eg. rand_num= [1 1 2 10 5 2 10] Thanks.

推荐答案

让我们

numbers = [1 2 4 10]; %// population to sample from
N = 5; %// how many samples to take

您可以使用 randsample (统计工具箱):

You can use randsample (Statistics Toolbox):

rand_num = randsample(numbers, N, true); %// "true" means sample with replacement

或 randi (标准功能):

or randi (standard function):

rand_num = numbers(randi(numel(numbers), 1, N));
