I am trying to create a button that has up/down arrows on the side that will scroll through numbers using a specified step size (the user will change it to arrive at a desired value)

Do I have to use an "edit text" box and add up down arrows or a scroll bar? I am not sure how to do this...

I am trying to scroll through timing values in msec from 0 to +900000

Any help is much appreciated

在 MATLAB Online 中打开

you can use a "slider" button , and "edit text" to set a "slider step" value

%opening function to set your slider parameters

function answer201_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
set(handles.slider1,'min',0)
set(handles.slider1,'max',10)
set(handles.slider1,'SliderStep',[0.01 0.1]);%minor step=0.01;major step=0.1

% slider function to show slider's value on static text button

 function slider1_Callback(hObject, eventdata, handles)
 w=get(hObject,'Value');
 set(handles.text1,'String',w)

% edit text function to change slider step value

function edit1_Callback(hObject, eventdata, handles)
step=get(hObject,'String')
min=double(get(handles.slider1,'min'))
max=double(get(handles.slider1,'max'))
stepn=str2num(step);
if stepn>min & stepn<max
  stepn1=stepn/(max-min)   ;
  set(handles.slider1,'SliderStep',[stepn1 stepn])
else
  set(hObject,'String',num2str((max-min)/10))
end
