hi all, is there an easy way of creating a subdiagonal matrix, that is with 1 just under the diagonal and 0's elsewhere ? this is for students, we'd like to convince them that sage is easy, so i'd rather not write a function myself (which of course would be easy). Apparently (i hear this from a colleague) these matrices (and their sums, transpose, etc) show up all the time in numerical stuff.
i know numpy does it, so is it there for sage matrices also ? thanks pierre --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
