cusp::plus_value< T > Struct Template Reference

Detailed description

template<typename T>
struct cusp::plus_value< T >

plus_value is a function object to add a constant value to a given element.

Tis a model of Assignable, and if x is an object of type T, then x+c must be defined and must have a return type that is convertible to T.
plus_value is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class plus_value<T>, and x is an object of class T, then f(x) returns x+c.

// v = [3, 3, 3, 3, 3]
