scipy.special.erfc#
- scipy.special.erfc(x, out=None) = <ufunc 'erfc'>#
- Complementary error function, - 1 - erf(x).- Parameters:
- xarray_like
- Real or complex valued argument 
- outndarray, optional
- Optional output array for the function results 
 
- Returns:
- scalar or ndarray
- Values of the complementary error function 
 
 - Notes - erfchas experimental support for Python Array API Standard compatible backends in addition to NumPy. Please consider testing these features by setting an environment variable- SCIPY_ARRAY_API=1and providing CuPy, PyTorch, JAX, or Dask arrays as array arguments. The following combinations of backend and device (or other capability) are supported.- Library - CPU - GPU - NumPy - ✅ - n/a - CuPy - n/a - ✅ - PyTorch - ✅ - ✅ - JAX - ✅ - ✅ - Dask - ✅ - n/a - See Support for the array API standard for more information. - References [1]- Steven G.
