Eigen::DenseCoeffsBase< Derived, DirectWriteAccessors > Class Template Reference

Detailed Description

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

Base class providing direct read/write coefficient access to matrices and arrays.

Template Parameters

Derived	Type of the derived class
DirectWriteAccessors	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, WriteAccessors> which defines functions to access entries read/write using operator().
