Detailed Description

template<typename Derived>
class Eigen::ArrayBase< Derived >

Base class for all 1D and 2D array, and related expressions.

An array is similar to a dense vector or matrix. While matrices are mathematical objects with well defined linear algebra operators, an array is just a collection of scalar values arranged in a one or two dimensionnal fashion. As the main consequence, all operations applied to an array are performed coefficient wise. Furthermore, arrays support scalar math functions of the c++ standard library (e.g., std::sin(x)), and convenient constructors allowing to easily write generic code working for both scalar values and arrays.

This class is the base that is inherited by all array expression types.

Template Parameters:

Derived

is the derived type, e.g., an array or an expression type.

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