Thank you very much for your advise, it solved my problem very well. Another problem trapped me. When I use the hinfsyn function, the internal command runs to sb10ad (out = sb10ad(n, m, np_, ncon, nmeas, gamma, P.A, P.B, P.C, P.D)), debugging cannot be performed, the console does not display content, and there is no error message.

using command control.hinfsyn(P,1,1).
P is calculated using the control.augw() command.
