[MITgcm-support] tsearch

[Yuan Lian]

Hi Angela,

You can replace tsearch line with the following:

%%%%%% the following only works for matlab version 2012 or later.
% Triangularize the data
tri=DelaunayTri(x,y);
if isempty(tri),
   warning('Data cannot be triangulated.');
   return
end

% Find the nearest triangle (t)
[t, bcs] = pointLocation(tri, xi, yi);

%%%%%%

Hope this helps.

Best,
Yuan
