I guess I could try to realize some of the two ideas. Do you know of a
serious Octave application where sorting is a bottleneck?
the search for neighbouring triangles in an unstructured mesh could be
an example.
An implemention is in the forge function:
http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/extra/msh/inst/MSH2Mtopprop.m
as a benchmark, given a large unstructured mesh 'msh' try
ngb = MSH2Mtopprop(msh, "n")
anyway, I actually beleive that memory consumption, not speed, is the
real bottleneck for this...
