I have made a gui with two sliders that I need to be dependent on each other. I have an equation that relates them (slider1=slider2/.156). I want to be able to move either slider and have the other slider move automatically based on this formula.

I have not programmed the sliders to work correctly, so if anything, I would love some help getting my sliders programmed.

thanks!

Suppose your are using GUIDE, on the slider2 callback

set(handles.slider1,'value',get(handles.slider2,'value')/.156)

if not using GUIDE just replace handles.slider1 by the slider1 handle

Simple example, move the slider of the bottom and watch the one in the top, please be carefull with the values.

hf=figure;
sh2 = uicontrol(hf,'Style','slider',...
                'Max',1,'Min',0,'Value',0.1,...
                'SliderStep',[0.05 0.2],...
                'Position',[30 20 150 30],...
                'Callback','set(sh1,''value'',get(sh2,''value'')/.156)');
sh1 = uicontrol(hf,'Style','slider',...
                'Max',10,'Min',0,'Value',5,...
                'SliderStep',[0.05 0.2],...
                'Position',[30 90 150 30]);
