How can i change slider's maximum value according to another slider?

Hi,

i would like to change slider's maximum value (slider2) according to another slider's value (slider1). My formula is simple. But i don't know how to change slider value. Here is my slider codes:

Slider 1

taper = get(hObject,'value') ;  
set(handles.texttaper,'string',num2str(taper)) ;
guidata(hObject,handles) 

Slider 2 (i would like to change maximum value of this)

function sliderrs_Callback(hObject, eventdata, handles)
rs = get(hObject,'value') ;
set(handles.textrs,'string',num2str(rs)) ;
guidata(hObject,handles) ;

Mustafa - in the callback for the first slider you could try something like

function slider1_Callback(hObject, eventdata, handles)
taper = get(hObject,'value') ;  
set(handles.texttaper,'string',num2str(taper));
set(handles.sliderrs, 'Max', taper);

But you would need to add some logic to make sure that the max value you are using (taper) is valid given the minimum value for that other slider else you may see warning messages like

Warning: slider control requires that Min be less than Max
Control will not be rendered until all of its parameter values are valid

Thank you,

how can i say: "if sliderrs max value < 0" in matlab syntax

try

if get(handles.sliderrs, 'Max') < 0
    % do something
end
