- I'm using Mathematica to generate some Fortran code. The 22
- expressions currently turn into about 256 lines of code (the longest
- expression is about 34 lines long) without use of Simplify or Factor.
- Applying Simplify to the expressions takes a long time (2638 minutes
- so far on an IBM RS/6000 with only 1 of the 22 finished), though it
- does shorten the code (down to 7 lines from 26 on the only expression
- that has been completed so far). Does anybody know of a better way of
- simplifying expressions? Has anybody written a package to optimize
- the fortran code that it output? Has anybody written a module that
- generates CM fortran code in terms of the shift calls?
-
- Dave.
