my parameters are as follows
beta=[1.3526,0.1405];
sigma1 = [9485,187];
eta = [80.2606,12.9895];
phi = [157,2456,25.4488];
a = [0.0.316;0,0];
my code is
cvx_begin
cvx_solver mosek
variables l(1,K) p(1,K)
expressions I(1,K) I_old(1,K) dc(K,K) c1(1,K) c2(1,K)
for k=1:K
I(k) = 0;
I_old(k) = 0;
dc(k,k) =1/(log(2)(p_old(k)+eta(k)+p_mphi(k)));
for j=k+1:K
I(k) = I(k)+ a(k,j).p(j);
I_old(k) = I_old(k)+ a(k,j).p_old(j);
c1(k) = log((p(k)+sigma1(k)+I(k)+p_mbeta(k))(eta(k)+p_mphi(k)))/log(2);
c2(k) = log((sigma1(k)+I_old(k)+p_mbeta(k))(eta(k)+p_mphi(k)+p_old(k)))/log(2);
dc(k,j) = a(k,j)/(log(2)(sigma1(k)+ I_old(k)+p_mbeta(k)));
end
end
obj = sum(zeta1.pow_abs(l,3)+p.T)+p_mT;%
minimize obj
subject to
for k=1:K
c1(k) - (c2(k)+ dc(k,
(p-p_old)’) >= (L-l(k))/10^5;
l(k)>=0;
l(k)<=L;
p(k)>=0;
end
cvx_end
but, the cvx result is failed
