In a gui, I used a push button with a callbackfunction.

p1 = uicontrol('Style','pushbutton','String','Browse','Position',[480,500,150,50],'callback',{@browse_button_Callback});

"Error:Too many input arguments" I am totally unaware of the mistake.

The first two inputs of a callback function are

See this for more info.

If those are your only inputs, remove the curly brackets around your function call.

p1 = uicontrol('Style','pushbutton','String','Browse','Position',[480,500,150,50],'callback',@browse_button_Callback);

Use the curly brackets to pass additional inputs to your callback function. For example

p1 = uicontrol(..., 'callback',{@browse_button_Callback, data});

will pass the 'data' variable as the third input to browse_button_callback().

If you're not passing additional inputs to your callback function, you should only have those first two inputs.

If that doesn't help, please provide the actual callback function.
