Strange syntax

[bigmealy]

Hi,

I am currently trying to understand what is happening in line 59 of the file
delaunayn.m
Firstly, I can't find any documentation around "__delaunayn__" as a seperate
function, so I can only assume that it's some special syntax relating to the
function itself. Can anyone shed any light?
I've also tried applying the curly braces modifier to my data to see what
the effect there is, but it tells me "matrix cannot be indexed with {".
Again, can anyone shed any light?

Many thanks,

Bigmealy

    53 function T = delaunayn (pts, varargin)
    54 
    55   if (nargin < 1)
    56     print_usage ();
    57   endif
    58 
    59   T = __delaunayn__ (pts, varargin{:});
