- This weakness has definitely been corrected in Maple V Release 2,
- now available for DEC and Sun workstations, and on other platforms soon.
- (For precise information on releases, send e-mail to info@maplesoft.on.ca)
-
- For Maple V Release 1, one is forced to massage the data into a form which
- is valid Maple input, as a list of lists for example.
- Yes this is not nice, which is why the problem has been addressed in Release 2.
