Celestial Computing with MATLAB


Welcome

Celestial Computing with MATLAB is a collection of MATLAB scripts, utility functions and data files that can be used to solve a variety of practical problems in celestial mechanics and astronomy.  These algorithms were developed using version 7.0 of MATLAB.  However, please note that the world map and binary ephemeris files provided as part of this package will only work on Windows compatible computers.

The cost of this software suite is $99.  It can be ordered using the secure and flexible e-commerce services provided by PayPal (www.paypal.com).  PayPal accepts online payments by credit card and a PayPal account is not required to make a purchase.  Before purchasing the software, please read the license agreement.  After placing your order, you will receive an email within 24 hours with a password that will permit you to extract the source code and any support data files.  This zipped file can be downloaded here.
