Hello,

I had a similar problem in the past, and it turned out that the problem IN DEED did not have a feasible solution!!!

Please try to check analytically if this is the case. For instance, you can easily check if your contraints are contradicting, of course if you have more than one [sorry, I did not look into your code in detail.]

Best.

thank you all. the problem was just a simple change in the M-file. so
it works, though it has no improvement on the results.
