Trying to solve the following code but showing the error “Disciplined convex programming error:”
%% power, p1, p2, K, Ith x and y are known
cvx_begin gp
variable P(6)
solve= x *sum(log(1 + P*y));
maximize( solve )
subject to
sum(P)<= Power;
sum(P(1:3))<= p1;
sum(P(4:6))<= p2;
(sum(K*P))<= Ith;
cvx_end
where is the problem and what is the solve??
thanks in advance

Do read that, but also note that you’ve specified programming mode—but you’re not using that correctly, either. Here are the rules for geometric programs, which yours violates in the solve
expression.
Try this please
cvx_begin
cvx_expert true
variable P(6)
solve= x sum(log(1 + P y));
maximize( solve )
subject to
sum(P)<= Power;
sum(P(1:3))<= p1;
sum(P(4:6))<= p2;
(sum(K*P))<= Ith;
cvx_end
