I have scattered data in 2D/3D. I wish to transform it onto a regular grid.
What is the difference between delaunay.m and TriScatteredInterp.m
Does TriScatteredInterp use delaunay triangulation? or some other method of triangulation (eg http://en.wikipedia.org/wiki/Minimum-weight_triangulation)?
thank you

TriScatteredInterp indeed uses Delaunay triangulation. The reason they are different in MATLAB is because TriScatteredInterp provides a framework to use the triangulation to perform interpolation. Delaunay on the other hand just provides the triangulation.
You can see under the "definition" section of TriScatteredInterp :
