Eigen::SkewSymmetricBase< Derived > Class Template Reference

#include <Eigen/src/Core/SkewSymmetricMatrix3.h>

Detailed Description

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

Base class for skew symmetric matrices and expressions.

This is the base class that is inherited by SkewSymmetricMatrix3 and related expression types, which internally use a three vector for storing the entries. SkewSymmetric types always represent square three times three matrices.

This implementations follows class DiagonalMatrix

Template Parameters

Derived

is the derived type, a SkewSymmetricMatrix3 or SkewSymmetricWrapper.
