CPXXdelcols and CPXdelcols

The routine CPXXdelcols/CPXdelcols deletes all the columns in a specified range.

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

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

Description

The routine CPXXdelcols/CPXdelcols deletes 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.

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 column to be deleted.
end: An integer that specifies the numeric index of the last column to be deleted.

Return

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

Example


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