Legend containing only specific plots

I have 10 curves in a plot, but only three of them should appear in the legend. For example, among 10 curves, just the first, 5th and 10th should be in the legend, how I can do this?

Here's my program:

x=1:0.5:15;
y1=x.^1
plot(x,y1)
hold on
y2=x.^1.2
plot(x,y2)
hold on
.
.
.
y10=x.^2.2
plot(x,y10)
Solution

  • You can use handles for the plots, and then specify the plots for the legend by their handles:

    x=1:0.5:15;
y(1,:)=x.^1;
y(2,:)=x.^1.2;
...
...
...
y(10,:)=x.^2.2;

for k=1:10
   h(k)=plot(x,y(k,:));
   hold on
end
legend([h(1) h(5) h(10)],'curve 1','curve 5','curve 10');
hold off
