How can i clear a plot that drawn in a subplot?

Hi everyone! I use subplot to draw two plots. How can i delete any plot on each subplot? Why i use clf(p1), plot on second subplot is deleted? My code:

subplot(2,1,1);
hold on
x1=(0:0.01:10);
y1=sin(x1);
p1=plot(x1,y1);
subplot(2,1,2)
hold on
x1=(0:0.01:10);
y2=sin(x1)+cos(x1);
p2=plot(x1,y2,'Color','r');
clf(p2)
clf(p1)

Use cla() instead of clf() and clear the axes instead of deleting the curve.

h1 = subplot(2,1,1);
hold on
x1=(0:0.01:10);
y1=sin(x1);
p1=plot(x1,y1);
h2 = subplot(2,1,2)
hold on
x1=(0:0.01:10);
y2=sin(x1)+cos(x1);
p2=plot(x1,y2,'Color','r');
cla(h2)
cla(h1)
