CPXdelsetrows

int CPXPUBLIC CPXdelsetrows(CPXCENVptr env, CPXLPptr lp, int * delstat)

Definition file: cplex.h

Include files: cplex.h

The routine CPXdelsetrows deletes a set of rows. Unlike the routine CPXdelrows, CPXdelsetrows does not require the rows to be in a contiguous range. After the deletion occurs, the remaining rows are indexed consecutively starting at 0, and in the same order as before the deletion.

Note

The delstat array must have at least CPXgetnumrows(env,lp) elements.

Example

 status = CPXdelsetrows (env, lp, delstat);

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`.
delstat	An array indicating the rows to be deleted. The routine `CPXdelsetrows` deletes each row `i` for which `delstat[i] = 1`. The deletion of rows results in a renumbering of the remaining rows. After termination, `delstat[i]` is either -1 for rows that have been deleted or the new index number that has been assigned to the remaining rows.

Returns:

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