Question

跪求大神解释，matlab代码 plot([area(2) area(2)],[area(3) area(4)],'-k',，，，这句什么意思啊？

这是相关部分代码quare_L=all_nodes.square_L;
area=all_nodes.area;
plot([area(2) area(2)],[area(3) area(4)],'-k',[area(2) square_L],[area(3) area(3)],'-k',[area(2) square_L],[area(4) area(4)],'-k');

Answer 1

第一题 matlab 代码 面积结果存放在变量 area 中

clear all

x= linspace(-10,10,1000);

y1=x.^2/8;

y2=64./(x.^2+16);

plot(x,y1)

hold on

plot(x,y2)

xlabel('x')

ylabel('y')
