NVCC and older versions of clang do not fully support `std::complex` on device, leading to either compile errors (Cannot call `__host__` function) or worse, runtime errors (Illegal instruction). For most functions, we can implement specialized `numext` versions. Here we specialize the standard operators (with the exception of stream operators and member function operators with a scalar that are already specialized in `<complex>`) so they can be used in device code as well. To import these operators into the current scope, use `EIGEN_USING_STD_COMPLEX_OPERATORS`. By default, these are imported into the `Eigen`, `Eigen:internal`, and `Eigen::numext` namespaces. This allow us to remove specializations of the sum/difference/product/quotient ops, and allow us to treat complex numbers like most other scalars (e.g. in tests). |
