can u pls check the following code for the mean of the image

[s t]=size(q);
ss=s(1);
y=zeros(ss);
i=1;j=1;
for n=1:1:t
for m=1:1:s
y(m,n)=q(i,j);
i=i+1;
end;
i=1;
j=j+1;
end
h1=[1 1 1;1 1 1;1 1 1];
a1=conv2(y,h1);
%mea = mean(mean(a1));
figure;
subplot(2,2,1);
imshow(x);
subplot(2,2,2);
imshow(a1);
subplot(2,2,3);

hist(a1(:),max(a1(:)));
