CPXXgetlb and CPXgetlb

The routine CPXXgetlb/CPXgetlb accesses a range of lower bounds on the variables of a CPLEX problem object.

int CPXXgetlb( CPXCENVptr env, CPXCLPptr lp, double * lb, CPXDIM begin, CPXDIM end )

int CPXgetlb( CPXCENVptr env, CPXCLPptr lp, double * lb, int begin, int end )

Description

The routine CPXXgetlb/CPXgetlb accesses a range of lower 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 a lower bound, then CPXXgetlb/CPXgetlb returns a value less 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.
lb: An array where the specified lower bounds on the variables are to be returned. This array must be of length at least (end-begin+1). The lower bound of variable j is returned in lb[j-begin].
begin: An integer specifying the beginning of the range of lower bounds to be returned.
end: An integer specifying the end of the range of lower bounds to be returned.

Return

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

Example


status = CPXgetlb (env, lp, lb, 0, cur_numcols-1);
