Call from .mat to GUI text

Hello, I have a function that counts the objects in an image from a web-cam every 30 minutes. (it's an infinite loop, but i make it stop at three for testing) What I want to do is to display in my GUI text-box and being always updated.
But I don't know how to call the values from the matrix of the counteds objects.
Thank for your help.
CODE:
function CalculaParticulas
vid = videoinput('winvideo', 1,'I420_1280x720');
set(vid,'ReturnedColorSpace','grayscale');
Densidad=1000;
VolumenMAX=pi*1000/(8E18);
VolumenMIN=pi*15.625/(8E18);
Caudal=0.01; %m3/min
i=1;
pause(2);%Dejamos 32 minutos de margen antes de empezar (en segundos)
while (1);
img{i} = getsnapshot(vid);
fname = ['img' num2str(i)];%que nombre le ponemos al archivo
imwrite(img{i}, fname, 'jpg');%guardar el archivo con formato
pause(2);%paramos 3minutos entre foto y análisis
img{i} = imread(['img' num2str(i)]);
% %imshow(img1)% Si queremos ver la imagen original
img2{i}=im2bw(img{i},graythresh(img{i}));
img2{i}=~img2 {i};
B=bwboundaries(img2 {i});
NumberOfParticle(i)=length(B);
% disp(['Hay ', num2str(NumberOfParticle), ' partículas'])
%hold on
%for k = 1:length(B)
%boundary = B{k};
%plot(boundary(:,2), boundary(:,1), 'g', 'LineWidth', 0.2);
%end
Concentracion(i,1)=NumberOfParticle(i)*VolumenMAX*Densidad/Caudal
Concentracion(i,2)=NumberOfParticle(i)*VolumenMIN*Densidad/Caudal
Concentracion(i,3)=(Concentracion(i,1)+Concentracion(i,2))/2
save('concentracion.mat','Concentracion');
i=i+1;
pause(5); %esperamos 27'
if i==3;
break;
end
end
CODE GUI
function varargout = Interfaz(varargin)
% INTERFAZ MATLAB code for Interfaz.fig
% INTERFAZ, by itself, creates a new INTERFAZ or raises the existing
% singleton*.
%
% H = INTERFAZ returns the handle to a new INTERFAZ or the handle to
% the existing singleton*.
%
% INTERFAZ('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in INTERFAZ.M with the given input arguments.
%
% INTERFAZ('Property','Value',...) creates a new INTERFAZ or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Interfaz_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Interfaz_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
