Description
The routine CPXdelcols() is used to delete all the columns in a specified range. The range is specified using a lower and upper index that represent the first and last column to be deleted, respectively. The indices of the columns following those deleted are decreased by the number of columns deleted.Return Value
The routine returns a zero on success, and a nonzero if an error occurs.Synopsis
CPXdelcols (CPXENVptr env,
CPXLPptr lp,
int begin,
int end);
CPXENVptr envThe pointer to the CPLEX environment as returned by one of the
CPXopenCPLEX routines.
CPXLPptr lpA pointer to a CPLEX LP problem object as returned by
CPXcreateprob().
int beginAn integer that indicates the numerical index of the first column to be deleted.
int endAn integer that indicates the numerical index of the last column to be deleted.
status = CPXdelcols (env, lp, 10, 20);
