On my web-page http://zhugayevych.me/maple/index.htm you will find a Maple worksheet example of sparse diagonalization in ALPS 2.0 for Windows. The direct links are: http://zhugayevych.me/maple/ALPS_example.mw (Maple worksheet only) and http://zhugayevych.me/maple/ALPS.zip (whole working folder).
If you will find an easier or more efficient way to run ALPS applications from Maple, please, let me know.
