scipp.atanh# scipp.atanh(x, *, out=None)# Element-wise inverse hyperbolic tangent. The input unit must be dimensionless. Parameters: x (scipp.typing.VariableLike) – Input data. out (Optional[TypeVar(VariableLikeType, Variable, DataArray, Dataset, DataGroup[Any])], default: None) – Optional output buffer. Returns: Same type as input – The inverse hyperbolic tangent values of the input.
