在matlab中绘制两个系列

Question

我想在一个图中绘制r1和r2的值，我该怎么做？

for i=1:10
r1=rand(1)
r2=max(rand(1,2))
end

感谢您的帮助！

Answer 1

有许多方法，这里有几个选项：

clc;
clear all, close all;

r1 = zeros(10, 1);
r2 = zeros(10, 1);
x = 1:10;

for i=1:10
    r1(i) = rand(1);
    r2(i) = max(rand(1,2));
end

figure('Name', 'Values of r1 and r2', 'NumberTitle', 'off');
hold on;
axis([0, 11, -0.5, 1.5])
plot(x, r1, '+', x, r2,'o'); %many possibilities and options here for line style
h = legend('r1', 'r2');
xlabel('index')
ylabel('value')

disp('press a key');
pause();
close all;

Answer 2

for i=1:10
r1(i)=rand(1)
r2(i)=max(rand(1,2))
end
plot(r1)
hold on 
plot (r2)
