Software Links

Download page for LINDO. We'll be using the ``Classic LINDO'' at the bottom of the link page, which is set up for Windows. We may also look at LINGO later.
Linux version of LINGO
The LINDO User's Manual is here. The "help" features don't seem to work using "wine" under Linux.
Directory for Maple downloads. Note that this is an old version, and is not compatible with new Mac OS. This does work well with either Windows or Linux/Ubuntu.
Links to LibreOffice, which includes free software that emulates Word and Excel.
Online linear system solver.
