Detailed Description

A collection of templates to wrapper cublas functions.

Note

The implementation in the cu file is wrapped inside the namepsace clause. This is not necessary in general, however, it is needed to avoid the old gcc compiler error (this is a gcc bug) which complains "no instance of function template matches the argument list const float".
