用于具有条件

Question

给出函数g1 = 1 - d / r1和g2 = 1 - d / r2 这里d = 1，r1和r2定义为范围1到10，间距为0.1。 我试图绘制g1 vs g2，只有那些介于0＆lt; = g1 * g2＆lt; = 1之间的值。

代码是

clc
clear all
close all

d = 1;
r1 = 0:0.1:10;
r2 = 0:0.1:10;
g1 = 1-(d./r1);
g2 = 1- (d./r2);

s1 = size(g1);
s2 = size(g2);
for i = 1:101
    e = g1(1,i);
  for j = 1:101
     if((e*g2(1,j)) <= 1 && (e*g2(1,j)>= 0))
        plot(g1(1,j),g2(1,j),'o')
        hold on
    end
end

end
