I noticed the following behavior today in Linear Algebra, which came up when trying to make an orthonormal basis. Does anyone know what is going on?
sage: a=(QQ^3).subspace([[1,0,1]]) sage: b=a.basis()[0] sage: b/b.norm() --------------------------------------------------------------------------- <type 'exceptions.TypeError'> Traceback (most recent call last) /home/grout/<ipython console> in <module>() /home/grout/element.pyx in sage.structure.element.Vector.__div__ (sage/structure/element.c:10962)() /home/grout/element.pyx in sage.structure.element.Vector.__mul__ (sage/structure/element.c:10413)() /home/grout/coerce.pyx in sage.structure.coerce.CoercionModel_cache_maps.bin_op_c (sage/structure/coerce.c:5292)() <type 'exceptions.TypeError'>: unsupported operand parent(s) for '*': 'Vector space of degree 3 and dimension 1 over Rational Field Basis matrix: [1 0 1]' and 'Symbolic Ring' Note that the following does work: sage: b=vector(QQ,[1,0,1]) sage: b/b.norm() (1/sqrt(2), 0, 1/sqrt(2)) Thanks, Jason --~--~---------~--~----~------------~-------~--~----~ 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://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
