A=imread( 'fingerprint.tif' );
%Structuring element
b = [0 1 0; 1 1 1; 0 1 0];
C=padarray(A,[0 3]);
D=false(size(A));
for i=1:size(C,1)
for j=1:size(C,2)-6
D(i,j)=sum(B&C(i,j:j+6));
end
end
figure(1),imshow(D);title('dilation');

You aren't using your structuring element. Is that on purpose? And do you need it to be a loop?

What is "B" here?
You are trying to "&" operation on two different sizes matrices???
here
b & C(i,j:j+6)

No, b is your structuring element, B doesn't exist. And you haven't explained if you need a loop or not.

Why not simply use imdilate()?
