)
Arguments
prob 
The current problem.
penalty 
The type of penalties created from the preferences:
c
each penalty is the reciprocal of the preference (default);
s
the penalties are placed in the scaled problem.
phase2 
Controls the second phase of optimization:
o
use the objective sense of the original problem (default);
x
maximize the relaxed problem using the original objective;
f
skip optimization regarding the original objective;
n
minimize the relaxed problem using the original objective;
i
if the relaxation is infeasible, generate an irreducible infeasible subset for the analys of the problem;
a
if the relaxation is infeasible, generate all irreducible infeasible subsets for the analys of the problem.
flags 
Specifies flags to be passed to optimize.
lepref 
Preference for relaxing the less or equal side of row.
gepref 
Preference for relaxing the greater or equal side of a row.
lbpref 
Preferences for relaxing lower bounds.
ubpref 
Preferences for relaxing upper bounds.
delta 
The relaxation multiplier in the second phase -1.
Return value
The status after the relaxation:
0
relaxed optimum found;
1
relaxed problem is infeasible;
2
relaxed problem is unbounded;
3
solution of the relaxed problem regarding the original objective is nonoptimal;
4
error (when return code is nonzero);
5
numerical instability;
6
analysis of an infeasible relaxation was performed, but the relaxation is feasible.
