CPXXunscaleprob and CPXunscaleprob
The routine CPXXunscaleprob/CPXunscaleprob removes any scaling that
CPLEX has applied to the resident problem and its associated data.
int CPXXunscaleprob( CPXCENVptrenv, CPXLPptrlp )
int CPXunscaleprob( CPXCENVptrenv, CPXLPptrlp )
Description
This is an advanced routine. Advanced routines typically demand a thorough understanding of the algorithms used by CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, the team encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.
The routine CPXXunscaleprob/CPXunscaleprob removes any scaling that
CPLEX has applied to the resident problem and its associated data. A side
effect is that if there is a resident solution, any associated factorization
is discarded and the solution itself is deactivated, meaning that it can no
longer be accessed with a call to CPXXsolution/CPXsolution, nor by any
other query routine. However, any starting point information for the current
solution (such as an associated basis) is retained.
