MATLAB: Does MATLAB have functions to generate, manipulate and visualize HEALPix (Hierarchical Equal Area isoLatitude Pixelization) data

Question

I would like to work with and visualize HEALPix data in MATLAB. A description of HEALPix from the project's website, http://healpix.jpl.nasa.gov, is as follows:

"HEALPix is an acronym for Hierarchical Equal Area isoLatitude Pixelization of a sphere. As suggested in the name, this pixelization produces a subdivision of a spherical surface in which each pixel covers the same surface area as every other pixel."

Does MATLAB have any functions that can handle such data?

Answer 1

The ability to generate and visualize HEALPix data is currently not available in MATLAB. In case you have any questions/clarifications regarding this, please feel free to contact Technical Support:

As a possible workaround, you can download the Java version of the HEALPix software,

and access/interface with MATLAB (refer to the following documentation pages regarding External Language Interfaces):
