I have 6 matrix as A=rand(10,10),B=rand(10,10),C=rand(10,10) and a=rand(10,10),b=rand(10,10),c=rand(10,10). i want to plot all elements as plot(a,A,'r*',b,B,'b+',c,C,'go'); i am able to plot this way but while calling legend i am facing problem.

i want legend('a','b','c'); where a will indicate red color *,b as blue + and c as green o.

 hold on
p1=plot(a,A,'or');
 p2=plot(b,B,'+b');
 p3=plot(c,C,'pg');
 legend([p1(1) p2(1) p3(1)], 'a','b','c');
