This tip, which seems the most effective and least likely to blow up, has made it to the following blog. http://doxdrum.wordpress.com/2011/01/22/sage-tip-simplifying-a-matrix/
So is it possible that this could become an approach to matrices, either automagically, or by a smarter map function? Proposal one: All method calls to matrices first try to find a method that is native to the matrix. Then if this fails, sage attempts to map the method to all the matrix elements. Proposal two: <matrix>.map accepts either a function OR a method name. If the function call fails, tries to apply as a method of each element. E.g. D.map(simplify_full) currently gives NameError: name 'simplify_full' is not defined Instead D.map(simplify_full) fails on the function call, but instead of returning NameError, it then tries Simon's approach, by doing an invisible call to self.map(lambda x: x.simplify_full) If that fails, then let the errors propagate back up. (Have to make sure that this semi-recursive approach doesn't result in an infinite recursion of course.)
