5  Scaling of optimal control problems

Scaling of optimal control problems are best done after they are defined. The level of the cost function, variables, states and controls should be balanced around 1.

PROPT does however, have an automated scaling feature that could be tested if needed. The option can be activated by setting:

 options.scale = 'auto';

shuttleEntry.m and minimumClimbEng.m exemplify how to use and enable the scaling of optimal control problems.
