Purpose
Recompute the dual steepest-edge norms.
Synopsis
int QScompute_row_norms (QSprob p)
Arguments
p a handle to an initialized problem.
Returns
A zero value if the function terminated correctly, and a non-zero value if an error occurred.
Description

Recomputes the dual steepest-edge norms for problem p. Note that an error will occur if the current dual pricing rule is not QS_PRICE_DSTEEP.

Example
/* p is an initialized QSprob, a handle to an existing LP problem.  */
/* Assume we are working with the QS_PRICE_DSTEEP pricing rule.     */

int rval;

rval = QScompute_row_norms (p);
if (rval) {
    fprintf (stderr,
             "Could not compute row norms, error code %d\n", rval);
}
