How to return multiple image as output results by the for-loop of the function into the main

I want to get all the segmented lines image results from my functions into the main, but it only returns the last line of the input image.

here is the function for line segmenter code:

function mat5 = charextract(ipimg)

%aa=imread('num_ip.tif');
bb=rgb2gray(ipimg);


cc=imbinarize(bb);

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%   SEGMENTATION    %%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

[x,y]=size(cc);
ee=sum(cc,2);
mat2=y-ee;
mat3=mat2~=0;
mat4=diff(mat3);
index1=find(mat4);
[q,w]=size(index1);%size of index2 matrix is q*w
kap=1;
lam=1;

while kap<((q/2)+1)%number of loops=number of lines
    k=1;
    mat5=([]);
       for j=(index1(lam)+1):1:index1(lam+1)
         mat5(k,:)=cc(j,:); %store the line segmented matrix
         %aadd{j}=mat5(k,:);
         k=k+1;
       end
       lam=lam+2;   
       kap=kap+1;
       %aa=mat5+1;
       %figure, imshow(mat5);
end

end

Here is the main code:

close all;
clear all;
clc;

img=imread('num_ip.tif');
img2=charextract(img);
imshow(img2);

It return only the segmented last line of the input image.
