CPXdelcols

int CPXPUBLIC CPXdelcols(CPXCENVptr env, CPXLPptr lp, int begin, int end)
Definition file: cplex.h

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.

Example

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

Parameters:

env

A pointer to the CPLEX environment as returned by CPXopenCPLEX.

lp

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

begin

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

end

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

Returns:

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