Likely it would still be faster than a solution with a loop (also because with the loop you'd loop over pairs of numbers). I'm fine with adding a note to the documentation (e.g. Imputing the missing values would, of course, be possible. Create a large matrix of points, and then measure the time used by pdist with the default "euclidean" distance metric. vectors.
