Eigen::EigenBase< Derived > Class Template Reference

Detailed Description

template<typename Derived>
class Eigen::EigenBase< Derived >

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.

Index

template<typename Derived >

typedef Eigen::Index Eigen::EigenBase< Derived >::Index

The interface type of indices.

To change this, #define the preprocessor symbol EIGEN_DEFAULT_DENSE_INDEX_TYPE.

See also

StorageIndex, Preprocessor directives. DEPRECATED: Since Eigen 3.3, its usage is deprecated. Use Eigen::Index instead. Deprecation is not marked with a doxygen comment because there are too many existing usages to add the deprecation attribute.
