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.
