XPRSgetredcosts

Purpose
Used to obtain the reduced cost values following optimization with XPRSoptimize.
Synopsis
int XPRS_CC XPRSgetredcosts(XPRSprob prob, int *status, double djs[], const int first, const int last);
Arguments
prob 
The current problem.
status 
Information about the reduced costs returned.
djs 
Double pointer where the reduced costs for the variable will be returned. May be NULL if not required.
first 
First column in the reduced costs.
last 
Last column in the reduced costs.
Further information
1. The function always returns data in the original space, even if the problem is currently in presolved state.
2. The status can take the same values as SOLSTATUS.
3. When reduced costs are available, the status returned will be the same as for XPRSgetsolution.
4. Can also be used after calling XPRSlpoptimize and XPRSmipoptimize however is it best practice to access the relevant solutions by XPRSgetlpsol and XPRSgetmipsol when a specific problem type has been optimized.
5. Cannot be used inside callbacks: use XPRSgetlpsol and XPRSgetmipsol instead.
