Sébastien Brisard updated MATH-682:
-----------------------------------
Attachment: PascalTriangle.java
Please find attached what I have for the moment. It needs some polishing to
meet the CM standards, I believe. Also, it is based on JScience, which has both
concepts of Field (like CM, but less convenient, I think) and Variable (which
allowed me to have a method to expand binomials. As this feature is absent from
CM, this would probably go).
Previously computed lines are indeed cached.
Please let me know if you think it's a good start.
As for me, I need this class to work with FieldElement, but if this is
far-fetched for CM, then I'm happy keeping this feature for the specific use I
have.
