Hello
I have a 2xN matrix where each column represent the x and y coordinates of a 2D point. I need to remove any duplicate point from this matrix, any suggestions?
Best regards MC

It would be very nice of you, if you could change the title of this question, it misleads others who are actually looking for the answers related to 'vector'. Thank you(:

It is trivial to use unique to get only the unique rows of matrix. Because your matrix is arranged 2xN, simply transpose before and after:
unique(M.','rows').'
