CPXXgetub and CPXgetub

The routine CPXXgetub/CPXgetub accesses a range of upper bounds on the variables of a CPLEX problem object.

int CPXXgetub( CPXCENVptr env, CPXCLPptr lp, double * ub, CPXDIM begin, CPXDIM end )

int CPXgetub( CPXCENVptr env, CPXCLPptr lp, double * ub, int begin, int end )

Description

The routine CPXXgetub/CPXgetub accesses a range of upper bounds on the variables of a CPLEX problem object. The beginning and end of the range must be specified.

Unbounded Variables

If a variable lacks an upper bound, then CPXXgetub/CPXgetub returns a value greater than or equal to CPX_INFBOUND.

Arguments

env: A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
lp: A pointer to a CPLEX problem object as returned by CPXXcreateprob/CPXcreateprob.
ub: An array where the specified upper bounds on the variables are to be returned. This array must be of length at least (end-begin+1). The upper bound of variable j is returned in ub[j- begin].
begin: An integer specifying the beginning of the range of upper bounds to be returned.
end: An integer specifying the end of the range of upper bounds to be returned.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.

Example


status = CPXgetub (env, lp, ub, 0, cur_numcols-1);
