functor check for nan

Reported by: Peter Owned by: Peter
Priority: minor Milestone: yat 0.5
Component: utility Version: trunk
Keywords: Cc:


a functor that return 0.0 if input is nan and 1.0 otherwise.

This can be used to calculate the corresponding weight of a number (or a whole range of numbers). See for example nan(const Matrix&, Matrix&) that could be implemented using this functor together with std::transform.

What to call such a functor? It is inspired by the function nan in Matrix, but I'm not sure nan is the best name.
