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 Extending MatrixBase (and other classes) by defining the preprocessor symbol EIGEN_ARRAY_PLUGIN
.

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.

Constructs a vector or row-vector with given dimension. This is only for vectors (either row-vectors or column-vectors), i.e. matrices which are known at compile-time to have either one row or one column.
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 Array() instead.

Eigen::Array< _Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols >::Array | ( | Index | rows, |

) |
constructs an uninitialized array with rows rows and cols columns.
This is useful for dynamic-size arrays. For fixed-size arrays, it is redundant to pass these parameters, so one should use the default constructor Array() instead.

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=.

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.

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