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.

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

Constructor & Destructor Documentation

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

EIGEN_STRONG_INLINE Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::Array ( Index  dim) [inline, explicit]

Constructs a vector or row-vector with given dimension.

Note that this is only useful for dynamic-size vectors. For fixed-size vectors, it is redundant to pass the dimension here, so it makes more sense to use the default constructor Matrix() instead.

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=.

Reimplemented from Eigen::PlainObjectBase< Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols > >.

template<typename OtherDerived >
EIGEN_STRONG_INLINE Array& Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::operator= ( const ArrayBase< 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.

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=.

void Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::swap ( ArrayBase< OtherDerived > const &  other) [inline]

Override MatrixBase::swap() since for dynamic-sized matrices of same type it is enough to swap the data pointers.
