Hi: Something funny is going on:
sage: MS = MatrixSpace(CC, 2, 2) sage: A = MS([[1,5],[3,-1]]) sage: A.eigenspaces() [ (4.00000000000000, [ (1.00000000000000, 1.00000000000000) ]), (-4.00000000000000, [ ]) ] sage: A.eigenspaces()[0] (4.00000000000000, [ (1.00000000000000, 1.00000000000000) ]) sage: A.eigenspaces()[1] (-4.00000000000000, [ ]) sage: MS = MatrixSpace(QQ, 2, 2) sage: A = MS([[1,5],[3,-1]]) sage: A.eigenspaces() [ (4, [ (1, 1) ]), (-4, [ (1, -5/3) ]) ] I find it strange that eigenspaces works for QQ but not for the larger field CC. Makes me think the problem isn't with eigenspaces at all ... Should I create a trac item under linear algebra or ??? - David Joyner --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
