New Revision: 42763
URL: http://svn.boost.org/trac/boost/changeset/42763
Log:
Renamed the extreme_value distribution to explicitly cite the type. This
conforms to the Boost.Math naming (temporary only) to support both min
and max variants of this distribution.
Added:
sandbox/random/boost/random/extreme_value_i_distribution.hpp
- copied, changed from r42757, /sandbox/random/boost/random/extreme_value_distribution.hpp
Removed:
sandbox/random/boost/random/extreme_value_distribution.hpp
