Detailed Description

template<typename Derived>
class Eigen::DenseCoeffsBase< Derived, DirectAccessors >

Base class providing direct read-only coefficient access to matrices and arrays.

Template Parameters

Derived

Type of the derived class

Note

DirectAccessors Constant indicating direct access

This class defines functions to work with strides which can be used to access entries directly. This class inherits DenseCoeffsBase<Derived, ReadOnlyAccessors> which defines functions to access entries read-only using operator() .
