MATLAB: What does c(:).’ mean? c should be a vector

By writing c(:)' you are making sure that the vector has the dimension 1xn, where n is the length of the vector, a row vector. However, there is a very important difference between c(:).' and c(:)', because they are not the same.

The difference is when you are working with complex vectors, for instance

tmp = (1:5) + 1i; 
tmp(:).'

which gives you each complex number in a row vector, compared to

tmp(:)'

which is giving you a row vector of the complex conjugate of each element.

MATLAB: Remove duplicates from vector

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').'
