Namespaces

 viennacl
 Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
 
 viennacl::linalg
 Provides all linear algebra operations which are not covered by operator overloads.
 
 viennacl::linalg::cuda
 Holds all CUDA compute kernels used by ViennaCL.
 

Functions

template<typename NumericT >
__global__ void viennacl::linalg::cuda::el_wise_mul_div (NumericT *matrix1, NumericT const *matrix2, NumericT const *matrix3, unsigned int size)
 Main CUDA kernel for nonnegative matrix factorization of a dense matrices. More...
 
template<typename NumericT >
void viennacl::linalg::cuda::nmf (viennacl::matrix_base< NumericT > const &V, viennacl::matrix_base< NumericT > &W, viennacl::matrix_base< NumericT > &H, viennacl::linalg::nmf_config const &conf)
 The nonnegative matrix factorization (approximation) algorithm as suggested by Lee and Seung. Factorizes a matrix V with nonnegative entries into matrices W and H such that ||V - W*H|| is minimized. More...
