Namespaces | |
namespace | viennacl |
Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them. | |
namespace | viennacl::linalg |
Provides all linear algebra operations which are not covered by operator overloads. | |
namespace | viennacl::linalg::host_based |
Holds all compute kernels with conventional host-based execution (buffers in CPU RAM). | |
namespace | viennacl::linalg::host_based::detail |
Helper functions for the host-based linear algebra backend. | |
