Interplanetary Mission Analysis

Welcome

This web site contains MATLAB scripts and Windows compatible computer programs which be used for interplanetary mission analysis. Computer applications are available as MATLAB scripts, executable programs and Fortran source code. The MATLAB scripts were created with version 7.2 (2006a). The Fortran executable programs were created with version 6.6c of Compaq Visual Fortran and version 11.1 of Intel Visual Fortran.

The software for sale at this web site can be purchased using the flexible and secure e-commerce features offered by PayPal (www.paypal.com). PayPal accepts online payments by credit card and a PayPal account is not required to make a purchase. Before placing an order, 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 or executable program and any support data files.

PLEASE NOTE: The MATLAB scripts marked with SNOPT were written for use with the SNOPT nonlinear programming (NLP) algorithm. MATLAB versions of SNOPT 6.0 for several computer platforms can be found at Professor Philip Gill’s web site which is located at http://scicomp.ucsd.edu/~peg/. A PDF version of the SNOPT user’s manual is also available at that website.
