template<typename Derived>
template<typename OtherDerived >
EIGEN_DEVICE_FUNC MatrixBase<Derived>::template cross_product_return_type<OtherDerived>::type Eigen::MatrixBase< Derived >::cross ( const MatrixBase< OtherDerived > &  other) const
inline
Returns
the cross product of *this and other

Here is a very good explanation of cross-product: http://xkcd.com/199/

With complex numbers, the cross product is implemented as $ (\mathbf{a}+i\mathbf{b}) \times (\mathbf{c}+i\mathbf{d}) = (\mathbf{a} \times \mathbf{c} - \mathbf{b} \times \mathbf{d}) - i(\mathbf{a} \times \mathbf{d} - \mathbf{b} \times \mathbf{c})$

template<typename ExpressionType , int Direction>
template<typename OtherDerived >
EIGEN_DEVICE_FUNC const VectorwiseOp< ExpressionType, Direction >::CrossReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::cross ( const MatrixBase< OtherDerived > &  other) const
Returns
a matrix expression of the cross product of each column or row of the referenced expression with the other vector.

The referenced matrix must have one dimension equal to 3. The result matrix has the same dimensions than the referenced one.

See also
MatrixBase::cross()

Definition at line 110 of file OrthoMethods.h.

template<typename Derived >
template<typename OtherDerived >
EIGEN_DEVICE_FUNC MatrixBase< Derived >::PlainObject Eigen::MatrixBase< Derived >::cross3 ( const MatrixBase< OtherDerived > &  other) const
inline
Returns
the cross product of *this and other using only the x, y, and z coefficients

The size of *this and other must be four. This function is especially useful when using 4D vectors instead of 3D ones to get advantage of SSE/AltiVec vectorization.

MatrixBase::cross()

Definition at line 82 of file OrthoMethods.h.

template<typename Derived >
EIGEN_DEVICE_FUNC Matrix< typename MatrixBase< Derived >::Scalar, 3, 1 > Eigen::MatrixBase< Derived >::eulerAngles ( Index  a0,
Index  a1,
Index  a2 
) const
inline
Returns
the Euler-angles of the rotation matrix *this using the convention defined by the triplet (a0,a1,a2)

Each of the three parameters a0,a1,a2 represents the respective rotation axis as an integer in {0,1,2}. For instance, in:

Vector3f ea = mat.eulerAngles(2, 0, 2);

"2" represents the z axis and "0" the x axis, etc. The returned angles are such that we have the following equality:

mat == AngleAxisf(ea[0], Vector3f::UnitZ())
* AngleAxisf(ea[1], Vector3f::UnitX())
* AngleAxisf(ea[2], Vector3f::UnitZ());

This corresponds to the right-multiply conventions (with right hand side frames).

The returned angles are in the ranges [0:pi]x[-pi:pi]x[-pi:pi].

template<typename Derived >
EIGEN_DEVICE_FUNC const MatrixBase< Derived >::HNormalizedReturnType Eigen::MatrixBase< Derived >::hnormalized ( ) const
inline

homogeneous normalization

Returns
a vector expression of the N-1 first coefficients of *this divided by that last coefficient.

This can be used to convert homogeneous coordinates to affine coordinates.

It is essentially a shortcut for:

this->head(this->size()-1)/this->coeff(this->size()-1);

Example:

Output:

column or row-wise homogeneous normalization 


Returns
an expression of the first N-1 coefficients of each column (or row) of *this divided by the last coefficient of each column (or row).


This can be used to convert homogeneous coordinates to affine coordinates.


It is conceptually equivalent to calling MatrixBase::hnormalized() to each column (or row) of *this.

Returns the transformation between two point sets. 


The algorithm is based on: "Least-squares estimation of transformation parameters between two point patterns", Shinji Umeyama, PAMI 1991, DOI: 10.1109/34.88573


It estimates parameters $ c, \mathbf{R}, $ and $ \mathbf{t} $ such that 

\begin{align*} \frac{1}{n} \sum_{i=1}^n \vert\vert y_i - (c\mathbf{R}x_i + \mathbf{t}) \vert\vert_2^2 \end{align*}



 is minimized.


The algorithm is based on the analysis of the covariance matrix $ \Sigma_{\mathbf{x}\mathbf{y}} \in \mathbb{R}^{d \times d} $ of the input point sets $ \mathbf{x} $ and $ \mathbf{y} $ where $d$ is corresponding to the dimension (which is typically small). The analysis is involving the SVD having a complexity of $O(d^3)$ though the actual computational effort lies in the covariance matrix computation which has an asymptotic lower bound of $O(dm)$ when the input point sets have dimension $d \times m$.


Currently the method is working only for floating point matrices.


Todo:
Should the return type of umeyama() become a Transform?


Parameters

  

    
srcSource points $ \mathbf{x} = \left( x_1, \hdots, x_n \right) $. 

    
dstDestination points $ \mathbf{y} = \left( y_1, \hdots, y_n \right) $. 

    
with_scalingSets $ c=1 $ when false is passed. 

  

  




Returns
The homogeneous transformation 

\begin{align*} T = \begin{bmatrix} c\mathbf{R} & \mathbf{t} \\ \mathbf{0} & 1 \end{bmatrix} \end{align*}


 minimizing the resudiual above. This transformation is always returned as an Eigen::Matrix.
