If your C++ code is called originally from Python, it's even easier (no need to embed an interpreter). It really depends on what you're doing, but easier than calling Sage might be looking into using LinBox directly (which ships with Sage). - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
