I doubt leaving this open is going to benefit anyone, so closing as won't do. The functions mentioned here are already part of Octave. If someone does want to look at performance, the attachment is still here for comparison.

As mentioned on the mailing list, it seems that these functions are already implemented in the lastest development version, see bugs #42688 and #42703, or the current implementations:

http://hg.savannah.gnu.org/hgweb/octave/file/827ac8b5ae07/scripts/linear-algebra/bandwidth.m

http://hg.savannah.gnu.org/hgweb/octave/file/827ac8b5ae07/scripts/linear-algebra/isbanded.m

http://hg.savannah.gnu.org/hgweb/octave/file/827ac8b5ae07/scripts/linear-algebra/isdiag.m

http://hg.savannah.gnu.org/hgweb/octave/file/827ac8b5ae07/scripts/linear-algebra/istril.m

http://hg.savannah.gnu.org/hgweb/octave/file/827ac8b5ae07/scripts/linear-algebra/istriu.m

However, after a very quick comparison it seem that these new implementation are slightly faster, but failed some of the tests. It may be worthy for someone to follow on this and try to mix the two.
