Astronomy & Astrophysics package for Matlab
The functions and data files are updated every week.
The Astronomy & Astrophysics package for MATLAB
includes over 800 MATLAB functions, and tens of data files
and astronomical catalogs, which are organized
in several toolboxes and several data/catalogs directories.
The scripts covers a wide range of subjects including:
astronomical image processing
catalog retrieval and searches
celestial maps and projections
ephemerides, time and coordinates manipulation
time series analysis
The catalogs and data files include selected astronomical catalogs
formated as MAT files, ephemerides tables, template spectra
The scripts were written by:
with contributions from:
In addition, included in this distribution
are several external matlab packages
(available also from:
Mathworks file exchange). These functions are included along with their license files.

or an acknowledgment:
"This work used the astronomy & astrophysics package for
Matlab (Ofek 2014)."
New important features:
(Jan-2016) Image subtraction tools will be added soon
(Jan-2016) Optimal image coaddition (see Zackay & Ofek 2015a, 2015b).
(Jun-2015) SIM (structure image array) class was added - the SIM is an image container in memory. It allows you to avoid excessive reading/writing of FITS images
(i.e., read and write once instead of multiple times). All the major function and arithmetics are supported.
You can populate a SIM with a catalog, mask, error etc, associated with the images.
Align images, cross match, and cross match with external catalogs.
(Mar-2015) New function for fast search of astronomical catalogs. HTM indexing of major catalogs.
(Jan-2015) New functions added for spectroscopic reduction.
