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.
• Links to LibreOffice, which includes free software that emulates Word and Excel.
• Online linear system solver.
  
  
• Here is a short video showing you how to install Maple on your home computer, should you want to try it out: NOTE ON THE VIDEO BELOW. Change the server name from winapp.whitman.edu to winapp3.whitman.edu. Because Maple goes to this server, you can only use it when you're on Whitman's network.
