How have the courts dealt with an appeal from a finding that a defendant was mentally unfit to stand trial for indecent exposure?

Defendant timely appealed from the judgment and we appointed counsel to represent him on appeal. Counsel filed a brief which set forth the facts of the case. She advised the court that she did not find any issues to argue on defendant's behalf, but identified the question of whether the evidence supported a finding he had the necessary mental state to support the indecent exposure convictions as a matter to be considered. Defendant was given 30 days to file written argument on his own behalf. That period has passed and we have received no communication from him. Pursuant to Anders v. California (1967) 386 U.S. 738 [87 S.Ct. 1396, 18 L.Ed.2d 493] and People v. Wende (1979) 25 Cal.3d 436, we have examined the record and find no arguable issue. Thus, we affirm the judgment.
