The linprog output structure now contains the constrviolation field, which reports
the maximum constraint function at the final point.
Compatibility Considerations
The interior-point algorithm of linprog might arrive at different solutions than before,
and can solve more problems than before.
Multiobjective optimValues Changes
The optimValues structure, used by output functions, has two new fields to better
reflect the state of multiobjective solvers:
For fgoalattain, the optimValues.attainfactor field contains the value of γ, the
attainment factor.
For fminimax, the optimValues.maxfval field contains the value max
i
F
i
, where F is
the vector of objectives.
Furthermore, the value stored in optimValues.fval has changed. Now
optimValues.fval contains the vector F of objective function values. For a complete
description of the current optimValues structure, see Fields in optimValues.
Compatibility Considerations
User code that uses the optimValues.fval field within an output function in
fgoalattain and fminimax might need to be updated to avoid errors
