I don't think that it should be the matrix consisting of absolute values of entries, since that only works for matrices over a ring with an absolute value. Using it as a determinant is consistent with standard notation, though I agree that we don't usually say absolute value in this context. In general, I'm opposed to matrix operations which do the same thing to each entry, unless we're very explicit about it. I would prefer a method 'elementwise()' which takes in a method (either the global function abs or the string 'abs') and applies it to teach entry. All this being said, I don't feel that strongly, so if other agree with Vincent, speak up.
