Hi All,

I'm trying to update my code for future the future. I have my own
triangulation source that returns the connections TRI for the points
X,Y. In the past I used tsearch to find the triangles that contained
the points. My problem now with 2010a is:

TSEARCH will be removed in a future release.
Use DelaunayTri/pointLocation instead.

The same goes for DSEARCH.

I'm relatively new to OOP in MATLAB. I tried the following:

>> TR = DelaunayTri();
>> TR.X = [X Y];
>> TR.triangulation = TRI;
??? Error using ==> subsasgn
Cannot assign values to the Triangulation.

I take it this means that triangulation is private,
that is I can only get its value. I noticed that as soon as I assigned
the points TR.X, the triangulation is performed. But I do not want
this triangulation, I want my own. At this time, all I really need is
the pointLocation method of DelaunayTri.

I tried using TriRep, but it does not include all of the mehtods from
DelaunayTri, especially pointLocation. Is it just me, or is MATLAB
just starting to get way to restrictive and more complicated than it
really needs to be?

Any help would be appreciated, as I found the MATLAB documentation not
very helpful.

Thanks
Rob
