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

, 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
