Detailed Description

template<typename ExpressionType, int Direction>
class Eigen::VectorwiseOp< ExpressionType, Direction >

Pseudo expression providing broadcasting and partial reduction operations.

Template Parameters

ExpressionType	the type of the object on which to do partial reductions
Direction	indicates whether to operate on columns (Vertical) or rows (Horizontal)

This class represents a pseudo expression with broadcasting and partial reduction features. It is the return type of DenseBase::colwise() and DenseBase::rowwise() and most of the time this is the only way it is explicitly used.

To understand the logic of rowwise/colwise expression, let's consider a generic case A.colwise().foo() where foo is any method of VectorwiseOp. This expression is equivalent to applying foo() to each column of A and then re-assemble the outputs in a matrix expression:

[A.col(0).foo(), A.col(1).foo(), ..., A.col(A.cols()-1).foo()]

Example:

Output:

The begin() and end() methods are obviously exceptions to the previous rule as they return STL-compatible begin/end iterators to the rows or columns of the nested expression. Typical use cases include for-range-loop and calls to STL algorithms:

Example:

Output:

For a partial reduction on an empty input, some rules apply. For the sake of clarity, let's consider a vertical reduction:

If the number of columns is zero, then a 1x0 row-major vector expression is returned.
Otherwise, if the number of rows is zero, then
- a row vector of zeros is returned for sum-like reductions (sum, squaredNorm, norm, etc.)
- a row vector of ones is returned for a product reduction (e.g., MatrixXd(n,0).colwise().prod())
- an assert is triggered for all other reductions (minCoeff,maxCoeff,redux(bin_op))

◆ rend() [2/2]

template<typename ExpressionType , int Direction>

const_reverse_iterator Eigen::VectorwiseOp< ExpressionType, Direction >::rend ( ) const

inline

const version of rend()

◆ replicate() [1/2]

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC const VectorwiseOp< ExpressionType, Direction >::ReplicateReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::replicate ( Index factor ) const

Returns: an expression of the replication of each column (or row) of *this

Example:

Output:

◆ replicate() [2/2]

template<typename ExpressionType , int Direction>

template<int Factor>

const Replicate< ExpressionType, isVertical *Factor+isHorizontal, isHorizontal *Factor+isVertical > EIGEN_DEVICE_FUNC Eigen::VectorwiseOp< ExpressionType, Direction >::replicate ( Index factor = Factor ) const

inline

Returns: an expression of the replication of each column (or row) of *this

Example:

Output:

◆ reverse() [1/2]

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC ReverseReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::reverse ( )

inline

Returns: a writable matrix expression where each column (or row) are reversed.

See also: reverse() const

◆ reverse() [2/2]

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC const ConstReverseReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::reverse ( ) const

inline

Returns: a matrix expression where each column (or row) are reversed.

Example:

Output:

See also: DenseBase::reverse()

◆ reverseInPlace()

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC void Eigen::VectorwiseOp< ExpressionType, Direction >::reverseInPlace

inline

This is the "in place" version of VectorwiseOp::reverse: it reverses each column or row of *this.

In most cases it is probably better to simply use the reversed expression of a matrix. However, when reversing the matrix data itself is really needed, then this "in-place" version is probably the right choice because it provides the following additional benefits:

less error prone: doing the same operation with .reverse() requires special care:
m = m.reverse().eval();
this API enables reverse operations without the need for a temporary

◆ squaredNorm()

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC const SquaredNormReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::squaredNorm ( ) const

inline

Returns: a row (or column) vector expression of the squared norm of each column (or row) of the referenced expression. This is a vector with real entries, even if the original matrix has complex entries.

Example:

Output:

See also: DenseBase::squaredNorm()

◆ stableNorm()

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC const StableNormReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::stableNorm ( ) const

inline

Returns: a row (or column) vector expression of the norm of each column (or row) of the referenced expression, avoiding underflow and overflow. This is a vector with real entries, even if the original matrix has complex entries.

See also: DenseBase::stableNorm()

◆ sum()

template<typename ExpressionType , int Direction>

EIGEN_DEVICE_FUNC const SumReturnType Eigen::VectorwiseOp< ExpressionType, Direction >::sum ( ) const

inline

Returns: a row (or column) vector expression of the sum of each column (or row) of the referenced expression.

Example:

Output:

See also: DenseBase::sum()
