Hi,
I have setup a uicontrol edit box into my code and expected to receive certain value from user. However, what kind of syntax can I use to get the value from the edit box to be used in other function?

You either set a callback function for that edit box, that will be triggered whenever the user hits the enter key,
edit = uicontrol('style','edit','Callback',@user_edit)
function user_edit(hObj,event) %these parameters are by default.
% hObj is the handle to your button.
disp(hObj.String) %this will display the current string
end
or, if you want to retrieve the string from beyond the callback function, assign a tag to your edit box so that you can point back to it:
set(edit,'Tag','edit1')
%or
edit.Tag = 'edit1';
function someotherfunction()
my_edit = findobj(gcf,'Tag',edit1);
disp(my_edit.String)
end

edit_speed = uicontrol('Style','edit','Position',[550,375,100,25],...
'Callback',{@newValueFromString});
function [ newValue, validNumber, inBounds ] = newValueFromString( ...
N, textString)
textString = get(edit_speed,'String');
[ inputNumber, validNumber ] = str2num( textString );
end
Is it possible for me to get the value of the input from the edit box and use it in other function using the code above?

yes, i mentioned that in my answer.
You can also store data in the 'UserData' property of your graphic objects.
so:
function [ newValue, validNumber, inBounds ] = newValueFromString( ...
N, textString)
textString = get(edit_speed,'String');
[ inputNumber, validNumber ] = str2num( textString );
edit_speed.UserData = textString
end
