Eigen::NoAlias class

Pseudo expression providing an operator = assuming no aliasing.

Template parameters
ExpressionType the type of the object on which to do the lazy assignment
StorageBase

This class represents an expression with special assignment operators assuming no aliasing between the target expression and the source expression.
