I want to use the SOSTOOLS toolbox, which works in Matlab and can be combined with the following SDP solvers: CSDP, SDPNAL, SDPA, SeDuMi, and SDPT3. I'm not sure about which of these solvers I should choose. Any advice would be welcome.
That would indeed be a rigorous way of making the decision, Cesáreo. However, I would rather avoid performing all of those tests :-) In fact, I'm asking because ideally I want to install & use only one solver
