Is it possible to declare and function within another function? if not, Look at the code below

% --- Executes on button press in Browse1.
function Browse1_Callback(hObject, eventdata, handles)
ExPath1 = fullfile(FilePath, FileName)
set(handles.Filename1,'string',ExPath1)
%-----------------------------------------------------------------------------
(I am trying use the ExPath1 variable from my Browse function in my calculate function, IS IT POSSIBLE TO USE THE ExPath1 VARIABLE? because I need it in order to do the calculation.)
%-----------------------------------------------------------------------------
%Calculate button code
function Calculate1_Callback(~, ~, ~)
[x, error, stat1, stat2, stat3] = correctionModelworking1(ExPath1,'true',2,'true');

More specifically:
function Calculate1_Callback(~, ~, handles)
ExPath1 = get(handles.Filename1, 'string');
x, error, stat1, stat2, stat3] = correctionModelworking1(ExPath1,'true',2,'true');
Provided, that is, that your callback is being passed handles, as would be the case if you are using GUIDE.

% --- Executes on button press in Calculate1.
function Calculate1_Callback(~, ~, ~)
% hObject handle to Calculate1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
%[x, error, stat1, stat2, stat3] = correctionModelworking1('landsat5.xls', 'true', 2,'true');
global shift fileName;
[~, ~, ~, ~, stat3] = correctionModelworking1(fileName, shift,'false',handles); %#ok<NASGU>
clear shift

As I indicated in my code, you need
function Calculate1_Callback(~, ~, handles)
If you use my code as written then you will not need the "global"

You either have to pass it in as an input to the second function, or make the second function nested:
function foo(stuff)
a = pi;
function baz()
a = a+1;
end
end
