Purpose
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.
