Theorem 6. If is strictly diagonally dominant by rows then satisfies for all . Proof. For we have . Let . Taking absolute values in gives. or , since .
WebJan 22, 2024 · When used in a CVX model, log_sum_exp(X) causes CVX's successive approximation method to be invoked, producing results exact to within the tolerance of the solver. This is in contrast to LOGSUMEXP_SDP, which uses a single SDP-representable global approximation. If X is a matrix, LOGSUMEXP_SDP(X) will perform its …
