Missing 'dsearch'

[Maarten D. de Jong]

While researching some of the geometry functions in the SF-repositry, I 
noticed that there is no 'dsearch'. Without it, no natural neighbours 
interpolation is possible---and that is a nasty surprise, because I had 
counted on using precisely that particular type of interpolation for my work.

Unfortunately, the MATLAB equivalent is (from what I can make out) labelled 
'private' and therefore not available as a straighforward .m-file, but only 
as a .dll. In other words, not in human-readable and thus portable, 
.oct-able format. Does anyone have a suggestion how to get dsearch to 
function on Octave?


Kind regards,
Maarten
