XPRSgetcolrange

---

Purpose

Returns the column ranges computed by XPRSrange.

Synopsis

int XPRS_CC XPRSgetcolrange(XPRSprob prob, double upact[], double loact[], double uup[], double udn[], double ucost[], double lcost[]);

Arguments

prob	The current problem.
upact	Double array of length COLS for upper column activities.
loact	Double array of length COLS for lower column activities.
uup	Double array of length COLS for upper column unit costs.
udn	Double array of length COLS for lower column unit costs.
ucost	Double array of length COLS for upper costs.
lcost	Double array of length COLS for lower costs.

Example

Here the column ranges are retrieved into arrays as in the synopsis:

int cols;
double *upact, *loact, *uup, *udn, *ucost, *lcost;
...
XPRSgetintattrib(prob,XPRS_COLS,&cols);
upact = malloc(cols*(sizeof(double)));
loact = malloc(cols*(sizeof(double)));
uup   = malloc(cols*(sizeof(double)));
udn   = malloc(cols*(sizeof(double)));
ucost = malloc(cols*(sizeof(double)));
lcost = malloc(cols*(sizeof(double)));
XPRSrange(prob);
XPRSgetcolrange(prob,upact,loact,uup,udn,ucost,lcost);

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.
