Upgrade to Computational Geometry
MATLAB includes a new object-oriented suite of computational geometry tools, together
with a new underlying library called CGAL. The new library provides improved
robustness, performance, and memory efficiency. The new tools are presented in three
classes:
• New class TriRep provides topological and geometric queries for triangulations in 2-D
and 3-D space.
• New class DelaunayTri provides increased functionality for Delaunay triangulation
including topological and geometric queries, incremental modification, and edge
constraints.
• New class TriScatteredInterp provides fast robust scattered data interpolation and a
new natural-neighbor interpolation technique.
Incomplete Inverse Gamma Function gammaincinv and Incomplete
Inverse Beta Function betaincinv
MATLAB has new functions for incomplete inverse gamma and incomplete inverse
beta functions. These functions, gammaincinv and betaincinv, provide the Statistics
and Machine Learning Toolbox functionality of the inverse incomplete gamma and beta
functions to MATLAB.
Krylov Subspace Methods bicgstabl and tfqmr
MATLAB has new iterative methods for solving systems of linear equations. bicgstabl
provides the stabilized biconjugate gradients method. tfqmr provides a transpose-free
implementation of the quasi-minimal residual method.
New Function quad2d
The quad2d function provides additional quadrature functionality for nonrectangular
areas of integration.
