MATLAB Code for Interpolating Triangulated Data

license - BSD language - MATLAB category - science status - maintained

The MATLAB code offers several functions for creating 2D triangulations and interpolating data:

  • creating triangulation from scattered data, using alpha shapes
    • handle ill-conditioned triangles
    • handle multiple (disjoint) domains
    • handle holes in the domains
  • removing ill-conditioned triangles
    • skinny triangles on the exterior boundary
    • triangles specified with a list of indices
  • computing the area and the angle of the triangles
  • linear interpolation on a specified triangulation
  • plotting triangulation geometry and data

Examples

Angles and Ill-conditioned Triangles

Triangulated and Interpolated Data

Compatibility

  • Tested with MATLAB R2021a.
  • No toolboxes are required.
  • Compatibility with GNU Octave not tested but probably easy to achieve.
