I'm having trouble using MsgBox.

kontrl = -4.796163466380676e-14

if -0.001<=kontrl & kontrl>=0.001
        h=msgbox({'Dengeli Ölçülerin Denetimi'   'BAŞARILI!!!'},...
    'Kontrol','custom',myicon);
elseif errordlg({'Dengeli Ölçülerin Denetimi' ' HATALI!!!'},'Hata');
end

"Conversion to logical from matlab.ui.Figure is not possible." I get this error.

What is class(myicon) ?

Also, please put in a breakpoint at the "if" and query class(kontrl)

"Myicon" is the photo.

elseif errordlg({'Dengeli Ölçülerin Denetimi' ' HATALI!!!'},'Hata');

I believe you wanted:

else
    errordlg({...},'Hata');

[Greg]

Which also means you aren't having any trouble using MsgBox as your question title states. You're having trouble using elseif.

I still have the same problem.
