New approach with own Symbol class, symbolic components and looser dependency
on sympy.


Revision 3496 - (view) (annotate) - [select for diffs]
Modified Wed Apr 6 03:58:42 2011 UTC (8 years ago) by caltinay
File length: 6821 byte(s)

symbolic functions.


Revision 3493 - (view) (annotate) - [select for diffs]
Modified Mon Apr 4 04:37:02 2011 UTC (8 years ago) by caltinay
File length: 6577 byte(s)
Diff to previous 3488
Removed escript's legacy Symbol implementation and replaced by a sympy-based
variant. Added more symbolic versions of escript functions and the relevant
unit tests.
This removes nearly 150000 (!) lines of code mainly from the old test suite for
symbols...wow!
