feasp in LMI syntax

Has anyone used feasp in the LMI syntax? Does it mean that it just check the feasibility of the system and give one possible answer, or it gives the final answer? thanks

[Archita P]

[TMIN,XFEAS] = feasp(LMISYS,OPTIONS,TARGET) solves the feasibility problem defined by the system of LMI constraints, LMISYS. When the problem is feasible, the output XFEAS is a feasible value of the vector of (scalar) decision variables.
