Hi, everybody,
I’m trying to solve a problem with CVX in SDP mode such as follows:
cvx_begin sdp
variables Ps(N) Psi(N);
variable W11(N,N) hermitian toeplitz;
variable W22(N,N) hermitian toeplitz;
minimize -(sum(log(1+Psi.*r1)))
subject to
[W11, diag(Psi);diag(Psi), W22]>=0;
cvx_end
where N is a constant, r1 is constant vector.
When N<=16, it can work. However, when N beomes larger (e.g. N=32), it will fail. The errors are listed as follows:
??? Index exceeds matrix dimensions.
error in ==> cvxprob/eliminate (line 170)
P = P( :, colX ) + P( :, cols ) * temp;
eroor in ==> cvxprob/solve (line 14)
[ At, cones, sgn, Q, P, dualized ] = eliminate( prob, true );
error in ==> cvx_end (line 77)
solve( prob );
error in ==> test0 (line 154)
cvx_end
I cann’t find out what’s wrong with it. Can anybody help me? Thanks a lot.
