XPRSbndsa

Purpose
Returns upper and lower sensitivity ranges for specified variables' lower and upper bounds. If the bounds are varied within these ranges the current basis remains optimal and feasible.
Topic areas
Sensitivity Analysis, LP
Synopsis
int XPRS_CC XPRSbndsa(XPRSprob prob, int ncols, const int colind[], double lblower[], double lbupper[], double ublower[], double ubupper[]);
Arguments
prob 
The current problem.
ncols 
Number of variables whose sensitivity is sought.
colind 
Integer array of length ncols containing the indices of the columns whose bounds' ranges are required.
lblower 
Double array of length ncols where the variable lower bound lower range values are to be returned.
lbupper 
Double array of length ncols where the variable lower bound upper range values are to be returned.
ublower 
Double array of length ncols where the variable upper bound lower range values are to be returned.
ubupper 
Double array of length ncols where the variable upper bound upper range values are to be returned.
Further information
XPRSbndsa can only be called when an optimal solution to the current LP has been found. It cannot be used when the problem is MIP presolved.
