Can you upload the code? nothing shows up. It is not clear on what you are trying to achieve with random numbers and the slider.

1. slider contains random numbers
2. Max value of slider is random.
3. or other

I have attached the code with my question. Its a notepad file. I need some random values when i move slider but i only get 1 whenever i move it.

Answer 1

This will be a 2 part solution. To answer your only get 1 you'll need to do something like this.

Button1 = uicontrol('Style', 'pushbutton', 'String', 'Run',...
'Position', [450 30 100 30],'Callback', {@edit_val,Slider1});

and then add an additional input to the function.

function edit_val(hobject, event,Slider1)

You are correct and the uicontrol passes the hobject and event, but those are for the uicontrol you are creating. Here the edit_val is not getting slider and event for the specified slider1. It is receiving the hobject and event for the associated pushbutton. I've included the Slider1 to pass the handle for slider1. Since we did that we need to add it to the function as an additional input.

I'm still thinking on how to get the random numbers within the sliders.

To get random values for the steps you can do something like this

Slider1 = uicontrol('Style', 'slider', 'Min',0,'Max', 10,...
'Position', [80 20 180 30],'Callback', @randomize);

Then have a function

function randomize(hobject, event)
    disp(get(hobject,'Value'));
    rando = 10*rand(1);
    set(hobject,'Value',rando);

where whenever something is moved you set it to a random number between 0 and 10?
