Eigen::ArrayWrapper< ExpressionType > Class Template Reference

Detailed Description

template<typename ExpressionType>
class Eigen::ArrayWrapper< ExpressionType >

Expression of a mathematical vector or matrix as an array object.

This class is the return type of MatrixBase::array(), and most of the time this is the only way it is use.
