Note

This is an advanced routine. Advanced routines typically demand a profound understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.

The routine CPXcopypnorms copies the primal steepest-edge norms to the specified LP problem object.

Parameters:

env	The pointer to the ILOG CPLEX environment, as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX LP problem object, as returned by `CPXcreateprob`.
cnorm	An array containing values to be used in a subsequent call to `CPXprimopt`, with a setting of `CPX_PARAM_PGRADIENT` of 2 or 3, as the initial values for the primal steepest-edge norms of the first `len` columns in the LP problem object. The array must be of length at least equal to the value of the argument `len`.
rnorm	An array containing values to be used in a subsequent call to `CPXprimopt` with a setting of `CPX_PARAM_PGRADIENT` of 2 or 3, as the initial values for the primal steepest-edge norms of the slacks and ranged variables that are nonbasic. The array must be of length at least equal to the number of rows in the LP problem object.
len	An integer that indicates the number of entries in the array `cnorm[]`.

Returns:

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