XPRSgetrowrange

---

Purpose

Returns the row ranges computed by XPRSrange.

Synopsis

int XPRS_CC XPRSgetrowrange(XPRSprob prob, double upact[], double loact[], double uup[], double udn[]);

Arguments

prob	The current problem.
upact	Double array of length ROWS for the upper row activities.
loact	Double array of length ROWS for the lower row activities.
uup	Double array of length ROWS for the upper row unit costs.
udn	Double array of length ROWS for the lower row unit costs.

Example

The following computes row ranges and returns them:

int rows;
double *upact, *loact, *uup, *udn;
...
XPRSrange(prob);
XPRSgetintattrib(prob,XPRS_ROWS,&rows);
upact = malloc(rows*sizeof(double));
loact = malloc(rows*sizeof(double));
uup   = malloc(rows*sizeof(double));
udn   = malloc(rows*sizeof(double));
...
XPRSgetrowrange(prob,upact,loact,uup,udn);

Further information

The activities and unit costs are obtained from the range file (problem_name.rng). The meaning of the upper and lower column activities and upper and lower unit costs in the ASCII range files is described in Appendix Log and File Formats.
