Follow-up Comment #4, patch #8559 (project octave):

Quick clarification: since the output `e' is meant to be the raw eigenvalues
output by `eig', the fixed `cmdscale' does *not* change the smallest
eigenvalue of `e' to 0. It only changes the set of coordinates given in the
output `X'. (Similarly, if `e' includes negative or complex eigenvalues, those
are unchanged in the output.)
