I have been assigned to run these codes and report what are they for. I'm good up to the 8th line. After that i'm lost and don't know what the last 3 lines do. I'll appreciate it if someone help me and explain what they do.
Thanks
a=rand(5);b=a;m=size(a,2);x=1:m;y=1:m;xx=x'*ones(1,m);yy=(y'*ones(1,m))';c=xx==yy;b(c)=0c=xx.^2>yy;a(c)=0
