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

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Derived & Eigen::DenseBase< Derived >::operator= ( typename OtherDerived  )

Copies other into *this.

Returns

template<typename Derived >
template<typename OtherDerived >
EIGEN_DEVICE_FUNC Derived & Eigen::DenseBase< Derived >::operator= ( typename OtherDerived  )

Copies the generic expression other into *this.

The expression must provide a (templated) evalTo(Derived& dst) const function which does the actual job. In practice, this allows any user to write its own special matrix without having to modify MatrixBase

Returns
a reference to *this.

Returns
an expression of the coefficient-wise power of the scalar x to the given array of exponents.

This function computes the coefficient-wise power between a scalar and an array of exponents.

Template Parameters
Scalaris the scalar type of x. It must be compatible with the scalar type of the given array expression (Derived::Scalar).

Example:

Array<double,1,3> e(2,-3,1./3.);
cout << "10^[" << e << "] = " << pow(10,e) << endl;
