How to get current status of the process in the edit box in gui matlab?

I have an existing code. Let it be c1.m. Now I have created a gui(c2.m ,c2.fig) for the user. I put an edit box for the current status of the process. Now what I want is whenever the code execution starts, the current status box should display the messages like featuring,extracting(just names) i.e., the entire process. How can I do that? One more problem that I am encountering is whenever I run code using GUI, the GUI automatically closing and it is opened after the completion of entire process.

Something equivalent in the code of the GUI:

handles.FigH  = figure('Tag', 'UniqueAndDescriptiveTagName');
handles.EditH = uicontrol('Style', 'Edit');
guidata(handles.FigH, handles);

And in the function for the calculations:

function YourCalculations
FigH = findobj(allchild(groot), 'flat', 'Tag', 'UniqueAndDescriptiveTagName');
if length(FigH) ~= 1
  error('Cannot find an open GUI');
end
handles = guidata(FigH);

% Just for demonstration:
for k = 1:10
  set(handles.EditH, 'String', datestr(now, 0));
  pause(0.2);
end

It might look smarter, if you start the calculations from a callback of the GUI, e.g. by a push-button. Then you can provide the required handles as inputs already:

function ButtonCallback(hObject, EventData, handles)
YourCalculations(handles);
end

And the header of the function the calculations:

function YourCalculations(handles)
set(handles.EditH, 'String', 'Started...');
...
end
