after write imerode function
i=imread('\cameraman.jpg');
B=im2bw(1,0.3);
K3=ones(3);
K5=ones(5);
K7=ones(7);
K9=ones(9);
B3=imerode(B,K3);
B5=imerode(B,K5);
B7=imerode(B,K7);
B9=imerode(B,K9);
imshow(B)
figure, imshow(B3), title('by 3');
figure, imshow(B5), title('by 5');
figure, imshow(B7), title('by 7');
figure, imshow(B9), title('by 9');
matlab stop and popup msg with matlab must be debug ?
what can i do ?
function imdilate show msg matlab has encountered an internal problem and need to close .
so how solve this problem ?

Does your MATLAB also stop working as soon as you draw any graphics? For example, does plot(3,5) cause problems?

FYI: The crash can be observed by doing this:
imerode(true, ones(3,3));
There is no crash observed for other strel sizes.

Alaa:
You've probably found a bug in imerode. However, I believe you really meant to do this instead:
B = im2bw(i, 0.3); % in this case, B is indeed the 256x256 matrix.
rather than
B = im2bw(1,0.3); % in this case, B is a scalar logical value of 1.
Doing so will not make MATLAB crash, but provide you the results you were originally looking for.
Hope this helps!

This is one of the reasons to avoid using i as a variable name.
