Hello
I am new to cvx and matlab. When I setup cvx in matlab using “cvx_setup” command, it sucessfully installs but I get the following warnings:
"

It gave me same message when I ran the example problem from cvx website:
">> m =20;
n =10;
p = 4;
A = random(m,n);
A = randn(m,n);
b = randn(m,1);
C=randn(p,n);
d = randn(p,1);
e = rand;
cvx_begin

minimize( norm(Ax - b,2))

norm(x,Inf)<=e
cvx_end

What did I do wrong? What should I do to avoid this warning everytime?
Thank you in advance!
