)  const [inline]
 

Returns true iff all matrix elements are equal within the given tolerance.

template<class ValueTypeT>
ValueTypeT osg::TransformationMatrix< ValueTypeT >::det3 (  void    )  const [inline]
 

Returns the determinat of the upper 3x3 submatrix.

template<class ValueTypeT>
ValueTypeT osg::TransformationMatrix< ValueTypeT >::det (  void    )  const [inline]
 

Returns the determinat of the whole 4x4 matrix.

template<class ValueTypeT>
bool osg::TransformationMatrix< ValueTypeT >::inverse (  TransformationMatrix< ValueTypeT > &    result )  const [inline]
 

Stores the inverse of the matrix into result, returns true if the matrix is not singular.

template<class ValueTypeT>
bool osg::TransformationMatrix< ValueTypeT >::invert (  void    )  [inline]
 

Inverts the matrix, returns true if the matrix is not singular.
