I just started to play around with "Hom()" and tryed to create a function mapping phi:x -> <x, ->; phi(x)(y) = <x,y> with <x,-> as element in Hom(ZZ^3,Z) and i was looking for a way to do this without using matrixes.
greatz Why precisely do you want to do this? Is it entirely so you can write > f(v), where f is in the dual and v is the space? If so, you could > make a new type called "DualFreeModuleElement" (say), which derives > from FreeModuleElement (defined in free_module_element.pyx), and give > it a different __call__ method, but leave everything else the same. > > -- William > > -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
