参数

n (int) -- number of rows
m (int) -- number of cols

all_cols(pbc: bool = False) → Sequence[Tuple[int, int]][源代码]#

return all col edge with 1d index encoding

参数: pbc (bool, optional) -- whether to include pbc edges (periodic boundary condition), defaults to False
返回: list of col edge
返回类型: Sequence[Tuple[int, int]]

all_rows(pbc: bool = False) → Sequence[Tuple[int, int]][源代码]#
