Details: - Updated test driver source in test, test/3, test/1m4m, and test/mixeddt to iterate through the problem space backwards. This can help avoid certain situations where the CPU frequency does not immediately throttle up to its maximum. Thanks to Robert van de Geijn for recommending this fix (originally made to test/sup drivers in57e422a). - Applied off-by-one matlab output bugfix fromb6017e5to test drivers in test, test/3, test/1m4m, and test/mixeddt directories.
