I'm a C++ developer, and would like to manipulate raw memory inside MatrixXd and VectorXd. Handling memory address can create many "shadow matrices" by combining different rows/columns, given their values are unchanged.
The data accessed by Eigen::MatraixXd.data( ) is empty, but the matrix actually holds non-empty values. I'm still confused by the Map method. It there a convenient way to directly manipulate memory in MatrixXd?
Thanks a lot.
