如何在MATLAB中从N个点中随机选择一个点?

本文介绍了如何在MATLAB中从N个点中随机选择一个点?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用以下代码创建和绘制N点:

I use this code to create and plot N points:

N = input('No. of Nodes:'); data = rand(N,2); % Randomly generated n no. of nodes x = data(:,1); y = data(:,2); plot(x,y,'*') hold on

我将如何随机选择这些点之一?

How would I randomly pick one of these points?

推荐答案

randnum=ceil(rand(1)*N) %Sample a random integer in the range 0 to N your_node = [x(randnum),y(randnum)] %Here is the sampled node from your data set Edit: changed floor to ceil.
