Detailed Description

template<typename ExpressionType, template< typename > class StorageBase>
class Eigen::NoAlias< ExpressionType, StorageBase >

Pseudo expression providing an operator = assuming no aliasing.

Template Parameters:
ExpressionTypethe type of the object on which to do the lazy assignment

This class represents an expression with special assignment operators assuming no aliasing between the target expression and the source expression. More precisely it alloas to bypass the EvalBeforeAssignBit flag of the source expression. It is the return type of MatrixBase::noalias() and most of the time this is the only way it is used.
