My code looks like this:
n=-180:180;
x=(pi/180).*n;
y=sin(x);
y2=sin(x).*cos(x);
y3=cos(x);
[ax h1 h2]=plotyy(n,y,n,y2)
h3=line(n,y3,'Color','r','LineWidth',2,'Parent',ax(1))
set(h1,'Color','k','LineStyle','-','LineWidth',1.0);
set(h2,'Color','b','LineStyle','-','LineWidth',1.5);
legend(ax(1),'h1','h3','Location','NorthEast')
legend(ax(2),{'h2'},'Location','NorthWest');
the last legend command is working

n=-180:180;
x=(pi/180).*n;
y=sin(x);
y2=sin(x).*cos(x);
y3=cos(x);
[ax h1 h2]=plotyy(n,y,n,y2)
h3=line(n,y3,'Color','r','LineWidth',2,'Parent',ax(1))
set(h1,'Color','k','LineStyle','-','LineWidth',1.0);
set(h2,'Color','b','LineStyle','-','LineWidth',1.5);
legend(ax(1),'h1','h3','Location','NorthEast')
% legend(ax(2),{'h2'},'Location','NorthWest');
but after disabling the last legend command

Please help how to keep both the legend boxes.

Use yyaxis:
n=-180:180;
x=(pi/180).*n;
y=sin(x);
y2=sin(x).*cos(x);
y3=cos(x);
yyaxis left
a=plot(n,y,'k')
legend('A')
yyaxis right
aa=plot(n,y2,'b')
hold on
aaa=plot(n,y3,'r')
legend([a aa aaa],{'A','B','C'})
