Suppress the following console output

My friend and I are making an SVM on our own (not using ML toolbox), and getting the following console output from a function we're using

"Minimum found that satisfies the constraints.

Optimization completed because the objective function is non-decreasing in 
feasible directions, to within the default value of the optimality tolerance,
and constraints are satisfied to within the default value of the constraint tolerance.

<stopping criteria details>."

How can we suppress this message? I looked at other answers and they don't seem to help us. Thanks!

>> fminunc(@(x) x.^2-1, 55)

Local minimum found.

Optimization completed because the size of the gradient is less than
the default value of the optimality tolerance.

ans =
     -6.16516743434659e-07
>> fminunc(@(x) x.^2-1, 55, optimoptions('fminunc','Display','none'))
ans =
     -6.16516743434659e-07
