fmincon output

Why does fmincon return the initial guess if the constraints are not compatible? It is extremely frustrating because if one wants to use fmincon over a loop, I cannot think of a way to distinguish between solutions found that fit the constraints and the "solution" given which is just the initial guess. If I could find a way to distinguish then that would be great!

===============

Use the exitflag output to determine why FMINCON stopped

[x,fval,exitflag]=fmincon(...)
