XPRSgetrowrange

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.
