int CPXgetbase (CPXCENVptr env, CPXCLPptr lp, int *cstat, int *rstat); |
The pointer to the CPLEX environment as returned by CPXopenCPLEX()
.
A pointer to a CPLEX problem object as returned by CPXcreateprob()
.
CPX_AT_LOWER | 0 | variable at lower bound |
CPX_BASIC | 1 | variable is basic |
CPX_AT_UPPER | 2 | variable at upper bound |
CPX_FREE_SUPER | 3 | variable free and non-basic |
Values for cstat[j]
:
CPX_AT_LOWER | 0 | associated slack/surplus/artificial variable non-basic at value 0.0 |
CPX_BASIC | 1 | associated slack/surplus/artificial variable basic |
For ranged rows, the array element rstat[i]
has the following meaning:
status = CPXgetbase (env, lp, cstat, rstat); |
