The function is preliminary and the order and number of its optional arguments can be expected to change. +New argument ``norm`` to fft functions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The default normalization has the direct transforms unscaled and the inverse +transforms are scaled by :math:`1/n`. It is possible to obtain unitary +transforms by setting the keyword argument ``norm`` to ``"ortho"`` (default is +`None`) so that both direct and inverse transforms will be scaled by +:math:`1/\\sqrt{n}`. + Improvements ============ |
