CPXdelcols

Description

The routine CPXdelcols() is used to delete all the columns in a specified range. The range is specified using a lower and an 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.

The routine returns a zero on success, and a nonzero if an error occurs.

CPXdelcols (CPXCENVptr env, CPXLPptr lp, int begin, int end);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

A pointer to a CPLEX problem object as returned by CPXcreateprob().

An integer that indicates the numerical index of the first column to be deleted.

An integer that indicates the numerical index of the last column to be deleted.

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