Hi,
I have A = zeros(100,100) materix which I added a while pixel (dots) in this zeros materix randomly. I have also another disc materix as follows
disk = strel('disk', 10);
D = disk.Neighborhood;
what I want to do is insert the disc and centered around the pixel ( white pixel)

A(appropriate_row:appropriate_row+99, appropriate_column:appropriate_column+99) = ...
A(appropriate_row:appropriate_row+99, appropriate_column:appropriate_column+99) | D;

The +99 should be +9
Protection needs to be added for the case that the location is near an edge.

Thank you for your reply. I did fix this as you says. it should be less than the disc raduis which is 10 in my case.
