the 3D matrix only contains one object. I want to know which of the two '1' values are the furthest away from each other. I read through all the functions and there doesn't seem to be a way. Is there one I don't know about?

Just do a brute force triple for loop. I attach a way in 2-D. A vectorized way would be to use find() and pdist2(), if you have the Statistics and Machine Learning Toolbox. Attach your 3-D binary image in a .mat file if you need more help. If you do that, let me know if you have the stats toolbox.
