problem during GUI closing

Hello to everyone, I have created a gui usin GUIDE and I put that in a function. I just want to freeze the main function script untill my GUI remains open, I have put a uiwait in the main function ( as below) and a uiresume in each button callback_function. I have put fprintf comand just to help me during debug to know witch part of the code was run.

Main Function

   function [ out_curve ] = customcrop_curve(curve)
%this function will crop approach and withdraw with  specifics x and y
%limits 

%store 
unchanged_curve= curve;
change=1;
%default limits
y_pos=0;
x_app=curve{1,2}(:,1);
x_pos=x_app(1);

%saving curve variable in a workspace that it will be recalled in the GUI
%(see GUI code for more information)

input_gui=0

save('temp_workspace')
fprintf('inizializzazionegui \n')  
h=adhesion_gui2fig;
%adhesion_gui2fig and customcrop_curve are in a parallel execution now

   %this comand stop execution until uiresume is called: uiresume is placed in
  %adhesion_gui2fig code in the push-bottons callback
uiwait(h)
fprintf('closing waiting \n')
  %still running gui
close (adhesion_gui2fig) %now it's closed

load('temp_workspace')

fprintf('gui closed \n')
%delete('temp_workspace.mat')

x_pos
y_pos

end

GUI

function varargout = adhesion_gui2fig(varargin)
% ADHESION_GUI2FIG MATLAB code for adhesion_gui2fig.fig
%      ADHESION_GUI2FIG, by itself, creates a new ADHESION_GUI2FIG or raises the existing
%      singleton*.
%
%      H = ADHESION_GUI2FIG returns the handle to a new ADHESION_GUI2FIG or the handle to
%      the existing singleton*.
%
%      ADHESION_GUI2FIG('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ADHESION_GUI2FIG.M with the given input arguments.
%
%      ADHESION_GUI2FIG('Property','Value',...) creates a new ADHESION_GUI2FIG or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before adhesion_gui2fig_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to adhesion_gui2fig_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

the proble is that when I push a Save or Exit button the gui close but in the matlab comand line is shown this:

   customcrop_curve(curve1)

 input_gui =

     0

 inizializzazionegui 
 slider creato 2 
 slider creato 1 
 first inizialization 
 axe populated 
 exit
 closing waiting 
 first inizialization 
 axe populated 
 gui closed 

 x_pos =

   -5.0802

 y_pos =

     0

as If after the button was pushed ('Exit_nochange' in this case) before the closeing instruction in the main function was run the entire Gui is reinitializated. Anyone could help me?
