Computational Geometry Functions Being Changed
2- and 3-D computational geometry functions (delaunay, convhull, griddata,
voronoi, delaunay3, griddata3) no longer use QHULL or the QHULL options
arguments. The N-D functions gridatan, delaunayn, convhulln, and voronoin still
use QHULL.
Compatibility Considerations
The QHULL options arguments to delaunay, convhull, griddata, and voronoi are
no longer required and are currently ignored. Support for these options will be removed
in a future release.
Computational Geometry Functions Being Removed
A future release will remove the griddata3, dsearch, tsearch, and delaunay3
functions. See the table below for alternatives.
Function Name Use This Method Instead
griddata3 TriScatteredInterp
dsearch DelaunayTri/nearestNeighbor
tsearch DelaunayTri/pointLocation
delaunay3 DelaunayTri
Compatibility Considerations
Update your old code to use the new computational geometry classes DelaunayTri and
TriScatteredInterp.
New Sparse Matrix Functionality In qr and mldivide Functions
mldivide supports complex rectangular sparse input matrices. qr supports complex
sparse input matrices. qr for sparse matrix input now supports a third output argument
that contains a fill-reducing permutation.
