Hello!
I am needing a very fast version of DelaunayTri + pointLocation. In fact, I am replacing:
t = tsearch(x,y,tri,xi,yi);
I have found that I can replace it with
DT = DelaunayTri(x,y);
t = pointLocation(DT,[xi yi]);
But I want a custom tri loaded from an existing saved file instead of calculating it with DelaunayTri. I am unable to load this custom tri into DT.Triangulation - MatLab won't let me edit the structure.
??? Error using ==> subsasgn
Cannot assign values to the Triangulation.
If I try to create my own structure, it tells me
??? Undefined function or method 'pointLocation' for input arguments of type
'struct'.
Is there any way to do this?
Thanks,
Joseph

Anyone? Guess it can't be done then...
