WebEigen::VectorXf u (size); the constructor that is called is Matrix::Matrix (int), in src/Core/Matrix.h. Besides some assertions, all it does is to construct the m_storage member, which is of type DenseStorage. You may wonder, isn't it overengineering to have the storage in a separate class? WebJan 8, 2016 · Unless setNbThreads has been called, Eigen uses the number of threads specified by OpenMP. You can restore this behavior by calling setNbThreads (0);.
