The simplest way to do this is probably M.conjugate() If you're not familiar with working with Python (which is the base language for Sage), at the "sage: " prompt, you can type foo.[TAB] and get a list of all "methods" associated with the object "foo". Sometimes, inspection of the list that is provided will give you some hints that will be worth trying out. For example, if "next" is in that list, typing foo.next? will get you (one hopes) an explanation of what the "next" method does, and possibly some examples of its use. Typing foo.next?? will get you that plus, possibly, the code that implements the method. Also, note that the "conjugate" method may not attach to your matrix, depending on the details of how you defined M, x, y. If this doesn't help, let us know. Justin -- Justin C.
