fmincon convergence - confusion with F-order optimality and Feasibility

Hi all,

I have am running optimization using fmincon however I am not sure if the results are satisfying.

I am a bit confused with "First order optimality" and "feasibility. I would expect that feasibility should go very close to zero. However, I read on matlab site that if the first order optimality value is very small, matlab does some futile iterations because it doesn't recognize that a minimum has reached.

Could you please let me know if I have understood correct?

I have attached also a screenshot of the optimization details to have a look

thanks in advance
