Help me please. I have this matrix, and I want to remove element (32,11) and (32,14) because it is close with (32,12). Can I do that?
Thank you.

a few difference is not something easy to code. Computers are not able to read your mind or guess what a few difference is. Is 1 a few? Is 10 a few? Is 0.1 a few? Is 1 million a few (it might be compared to the number of atoms in the universe)?
An actual numeric tolerance (relative or absolute), on the other hand, is very easy to code.

Read about pdist2. This will give pairwise distance . Now remove the points which you want to rmove by setting a tolerance in distance.
