Classes
struct	viennacl::gibbs_poole_stockmeyer_tag
	Tag class for identifying the Gibbs-Poole-Stockmeyer algorithm for reducing the bandwidth of a sparse matrix. More...

Namespaces
	viennacl
	Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
	viennacl::detail
	Holds implementation details for functionality in the main viennacl-namespace. Not intended for direct use by library users.
