Celestial
Computing with Numerit Pro
Welcome
This web site describes Numerit Pro applications that can be
used to solve a variety of practical problems in celestial mechanics and
astronomy. Numerit Pro is an integrated scientific
software development environment which is inexpensive ($99) yet powerful
and easy to use. This environment
includes a program editor, equation editor, report writer, debugging features
and interactive graphics. Additional
information about Numerit Pro,
including an evaluation version for download and the free Numerit Run run-time program, can be
found at www.numerit.com.
The
applications described here were developed with version 1.7 of Numerit Pro. The executable versions of the software
require the free Numerit Run program which is
also available at the Numerit web site.
