template<typename Derived>
Eigen::EigenBase class

Contents

Common base class for all classes T such that MatrixBase has an operator=(T) and a constructor MatrixBase(T).

In other words, an EigenBase object is an object that can be copied into a MatrixBase.

Besides MatrixBase-derived classes, this also includes special matrix classes such as diagonal matrices, etc.

Notice that this class is trivial, it is only used to disambiguate overloaded functions.
