CPXXdelqconstrs and CPXdelqconstrs

The routine CPXXdelqconstrs/CPXdelqconstrs deletes a range of quadratic constraints.

int CPXXdelqconstrs( CPXCENVptr env, CPXLPptr lp, CPXDIM begin, CPXDIM end )

int CPXdelqconstrs( CPXCENVptr env, CPXLPptr lp, int begin, int end )

Description

The routine CPXXdelqconstrs/CPXdelqconstrs deletes a range of quadratic constraints. A lower and upper index specify the range of quadratic constraints to delete. The lower index represents the first constraint to be deleted, and the upper index represents the last quadratic constraint to be deleted. CPLEX decreases the indices of the constraints following the deleted constraints by the number of deleted constraints.

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.
begin: An integer that specifies the numeric index of the first quadratic constraint to be deleted.
end: An integer that specifies the numeric index of the last quadratic constraint to be deleted.

Return

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

Example


 status = CPXdelqconstrs (env, lp, 10, 20);
