It is true that most software and some websites use the more intuitive definition that you were expecting. However a large part of the theoretical literature uses the transposed definition, since it can be more convenient mathematically. See for instance Mark Newman's book. In any case, this an unimportant issue. A matrix transpose can be obtained trivially in numpy. Best, Tiago -- Tiago de Paula Peixoto <ti...@skewed.de>
