Question

matlab作图，要求在y1,y2,y3一个图内，y4,y5,y6在一个图，只要用不同线型标记，拜托了！0=<x<=250

y1=3438.87;
y2={[(480000-(3438.87/0.005)]*1.005^(x-1)+(3438.87/0.005)}*0.005;
y3=3438.87-{[(480000-(3438.87/0.005)]*1.005^(x-1)+(3438.87/0.005)}*0.005;
y4=2000+[480000-2000*(x-1)]*0.005;
y5=2000;
y6=[480000-2000*(x-1)]*0.005;
图像和编码请一起发送！

Answer 1

x=0:0.01:250;%x从0到250的变化率为0.01
 y1=3438.87;

a=(480000-3438.87/0.005)*1.005.^(x-1);
 y2=(a+3438.87/0.005)*0.005;

y3=3438.87-(a+3438.87/0.005)*0.005; 

figure(1)

plot(x,y1,x,y2,x,y3)

y4=2000+(480000-2000*(x-1))*0.005;

y5=2000;

y6=(480000-2000*(x-1))*0.005;

figure(2)

plot(x,y4,x,y5,x,y6)

 

还有几种方法，就是加title，加网格之类的，目测楼主不需要，就这样了，望楼主采纳啊！！
