+% VSDP gives the possibility to choose via global parameters
+% alternative numerical ways:
+
+% Choice of the SDP-solver in MYSDPS 
+% VSDP_CHOICE_SDP = 1: SDPT3 solver
+% VSDP_CHOICE_SDP = 2: SDPA solver
+% DEFAULT = 1;
+global VSDP_CHOICE_SDP; VSDP_CHOICE_SDP = 1;
+
+% Choice, whether in VULS the interval system is solved as a full
+% system, or as a sparse system by computing the sdp matrix B*B';
+% VSDP_CHOICE_FULL = 0 in the latter case, recommended only for very.
+% large system. DEFAULT = 1;
+global VSDP_CHOICE_FULL; VSDP_CHOICE_FULL = 1;
+
+% Choice, whether during the iteration VSDPLOW and VSDPUP 
+% the last approximate solution is used as a starting point
+% for the next step (VSDP_USE_STARTING_POINT = 1), or not 
+% (VSDP_USE_STARTING_POINT = 0 is DEFAULT);
+global VSDP_USE_STARTING_POINT; VSDP_USE_STARTING_POINT = 0;
+
+% Choice of the maximal number of iterations in VSDP
+% DEFAULT = 5;
+global VSDP_ITER_MAX; VSDP_ITER_MAX = 9;
+
+% Choice of the perturbation parameter; DEFAULT = 1.5;
+global VSDP_ALPHA; VSDP_ALPHA = 1.5;
+
+
+
+
+% Using higher precision for computing the defects in VULS:
+% VSDP_HIGHER_PREC = 0 implies usual interval arithmetic, otherwise 
+% we use the INTLAB function DOT_ with quadruple precision
+% DEFAULT = 0;
+global VSDP_HIGHER_PREC; VSDP_HIGHER_PREC = 0;
