Parameters ---------- a : ndarray Input array of size (M, N) Returns ------- lu : tuple 2-tuple of ints indicating the lower and upper bandwidth. A zero denotes no sub- or super-diagonal on that side (triangular), and, say for M rows (M-1) means that side is full. Same example applies to the upper triangular part with (N-1). .. seealso:: :func:`scipy.linalg.bandwidth` r)rrÚ F_CONTIGUOUS) ÚcupyÚasarrayÚsizerÚ _assert_2dÚflagsÚTÚshapeÚmgridÚ_kernel_cupy_band_pos_cÚintÚamaxÚamin) ÚaÚAÚmÚnÚrow_numÚcol_numÚbandptsÚ upper_bandÚ lower_band©rúS/home/ubuntu/.local/lib/python3.10/site-packages/cupyx/scipy/linalg/_array_utils.pyÚ bandwidth s"       ýr)rÚ cupy.linalgrÚElementwiseKernelr rrrrrÚs ü
