Yes, but the import statement is very similar to the one in the numeric_array method in in matrix.py. If I attach a *.sage file are the rules for import statements different than if a *.py file is preloaded as part of SAGE? I was assuming they were the same. (To answer William's question about Numeric's eigenvalues command): I'm assuming that the Numeric docs at http://numpy.scipy.org/numpydoc/numpy-18.html#pgfId-303047 are correct. For example, sage: MS = MatrixSpace(RR,4,4) sage: A = MS([[1,2,3,4],[4,3,2,1],[4,5,6,7],[5,4,3,5]]) sage: import Numeric sage: n = len(A[0]) sage: AN = Numeric.reshape(A.list(),(n,n)) works just fine. > david > > > > > --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] 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/ -~----------~----~----~----~------~----~------~--~---
