Llamar a una función cada ver que se modifique el Value de un slider

Buenas tardes.

Mi problema es que necesito que se llame a una función cada ver que el usuario varie el valor de un slider. Lo he provado de poner la llamada a la función en el call_back, Button_Down y el Key_pres, y en ninguno funciona.

¿Alguien sabe como se puede hacer?

Good afternoon.

My problem is that I need to call a function every view the user to vary the value of a slider. I've proven to put the function call in the call_back, Button_Down and Key_pres, and none works.

Does anyone know how to do?

Have a text label right above the slider. In the regular callback (for slider1_Callback or something like that), have this

% Get the slider value.  The slider tag is slider1.
sliderValue = get(handles.slider1, 'Value');
% Make a string with the value in it.
caption = sprintf('The slider value = %.3f', sliderValue);
% Send the string to the static text control.
% The tag for the static text label above the slider is sliderText.
set(handles.sliderText, 'String', caption);
