Detailed Description

template<typename _Scalar, int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>
class Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >

General-purpose arrays with easy API for coefficient-wise operations.

The Array class is very similar to the Matrix class. It provides general-purpose one- and two-dimensional arrays. The difference between the Array and the Matrix class is primarily in the API: the API for the Array class provides easy access to coefficient-wise operations, while the API for the Matrix class provides easy access to linear-algebra operations.

See documentation of class Matrix for detailed information on the template parameters storage layout.

This class can be extended with the help of the plugin mechanism described on the page TopicCustomizing_Plugins by defining the preprocessor symbol EIGEN_ARRAY_PLUGIN.

Constructor & Destructor Documentation

◆ Array() [1/5]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::Array ( )

inline

Default constructor.

For fixed-size matrices, does nothing.

For dynamic-size matrices, creates an empty matrix of size 0. Does not allocate any array. Such a matrix is called a null matrix. This constructor is the unique way to create null matrices: resizing a matrix to 0 is not supported.

Member Function Documentation

◆ coeff() [1/2]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const Scalar& Eigen::PlainObjectBase< Derived >::coeff

inline

This is an overloaded version of DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index) const provided to by-pass the creation of an evaluator of the expression, thus saving compilation efforts.

See DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index) const for details.

◆ coeff() [2/2]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const Scalar& Eigen::PlainObjectBase< Derived >::coeff

inline

This is an overloaded version of DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index,Index) const provided to by-pass the creation of an evaluator of the expression, thus saving compilation efforts.

See DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index) const for details.

◆ coeffRef() [1/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Scalar& Eigen::PlainObjectBase< Derived >::coeffRef

inline

This is an overloaded version of DenseCoeffsBase<Derived,WriteAccessors>::coeffRef(Index) const provided to by-pass the creation of an evaluator of the expression, thus saving compilation efforts.

See DenseCoeffsBase<Derived,WriteAccessors>::coeffRef(Index) const for details.

◆ coeffRef() [2/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const Scalar& Eigen::PlainObjectBase< Derived >::coeffRef

inline

This is the const version of coeffRef(Index) which is thus synonym of coeff(Index). It is provided for convenience.

◆ coeffRef() [3/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Scalar& Eigen::PlainObjectBase< Derived >::coeffRef

inline

This is an overloaded version of DenseCoeffsBase<Derived,WriteAccessors>::coeffRef(Index,Index) const provided to by-pass the creation of an evaluator of the expression, thus saving compilation efforts.

See DenseCoeffsBase<Derived,WriteAccessors>::coeffRef(Index,Index) const for details.

◆ coeffRef() [4/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const Scalar& Eigen::PlainObjectBase< Derived >::coeffRef

inline

This is the const version of coeffRef(Index,Index) which is thus synonym of coeff(Index,Index). It is provided for convenience.

◆ operator=() [1/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Array& Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::operator= ( const Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols > & other )

inline

This is a special case of the templated operator=. Its purpose is to prevent a default operator= from hiding the templated operator=.

◆ operator=() [2/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

template<typename OtherDerived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Array& Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::operator= ( const DenseBase< OtherDerived > & other )

inline

Copies the value of the expression other into *this with automatic resizing.

*this might be resized to match the dimensions of other. If *this was a null matrix (not already initialized), it will be initialized.

Note that copying a row-vector into a vector (and conversely) is allowed. The resizing, if any, is then done in the appropriate way so that row-vectors remain row-vectors and vectors remain vectors.

◆ operator=() [3/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

template<typename OtherDerived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Array& Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::operator= ( const EigenBase< OtherDerived > & other )

inline

The usage of using Base::operator=; fails on MSVC. Since the code below is working with GCC and MSVC, we skipped the usage of 'using'. This should be done only for operator=.

◆ operator=() [4/4]

template<typename _Scalar , int _Rows, int _Cols, int _Options, int _MaxRows, int _MaxCols>

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Array& Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::operator= ( const Scalar & value )

inline

Set all the entries to value.
