The following no longer compiles: #include <complex> #include "Eigen/Core" template <typename Scalar = double> using Matrix = Eigen::Matrix<Scalar, Eigen::Dynamic, 1>; Matrix<std::complex<double>> v; Matrix<double> y; v.setRandom(5); y.setRandom(5); v.array() /= y.array(); It hits the mixed type assert: ./third_party/eigen3/Eigen/src/Core/AssignEvaluator.h:778:3: error: static_assert failed "YOU_MIXED_DIFFERENT_NUMERIC_TYPES__YOU_NEED_TO_USE_THE_CAST_METHOD_OF_MATRIXBASE_TO_CAST_NUMERIC_TYPES_EXPLICITLY" This seems too strict and a clear regression.
