Influence of the constraints on the vector x

Hello, please i made a simulation on a file.m for the function fmincon and by changing the constraints I find the same vector x. Do you have an explanation ? I used the structure x = fmincon (problem), and attached code captures. Thank you

x=0 is the global minimum of your objective.

Since x=0 satisfies the constraints in both cases, the solution remains the same.

thank you for the answer. Why do you think the vector x is different from the null vector yet the null vector is the global minimum of the function?

[Torsten]

I mean that since x=0 is the global minimum of your objective and x=0 satisfies the constraints you imposed in both cases under consideration, x=0 should be the solution to both of your problems. Is this not the case ?

Hello, sorry for the delay. In fact, I have not received any notifications from your comment! Well, the solution that is displayed to me is:

Those values are 0 to within the tolerance you have in effect.

Okay! Thanks a lot Cheers
