I am writing a program for fluid kinematics. It is working, but i want to show in matlab gui.

function ut=u(x,y);

ut=3*x+y

end

it accepts

function ut=u(x,y);

ut=(get(handles.edit11,'String'))

end

but it does not accept it.

i want to get values from edit_text. Can you help for this?

    ut = handles.edit11.String
    evalc(ut)
end

Shouldn't there be a get ...

get(handles.edit11,'String')

No - that's the old fashioned way - pre release 2014b. The newer way is like the object oriented programming (OOP) way that all modern languages use now. I'm using the new/current OOP way.
