Re: [Boost-users] [Proto] Questions about deep_copy

Hi Joel , thanks for your reply. But i doubt that BOOST_PROTO_AUTO could solve this problem, because it copies all values no matter for arrays. Since this can cause a large amount of data to copy this would definitely slow down for example matrix-vector multiplication. What i want is that deep_copy should copy only single values like double, float or int and not arrays. B/Rgds Kim Joel Falcou schrieb:

There is BOOST_PROTO_AUTO that solves this problem IIRC by providing the proper deep_copy call during the "auto" evaluation
