void prod_impl(const matrix_base< NumericT > &mat, bool trans_A, const vector_base< NumericT > &vec, vector_base< NumericT > &result)
Carries out matrix-vector multiplication.
Various little tools used here and there in ViennaCL.
This file provides the forward declarations for the main types used within ViennaCL.
A Vandermonde matrix class.
Definition: forwards.h:418
Common base class for dense vectors, vector ranges, and vector slices.
Definition: vector_def.hpp:104
The vector type with operator-overloads and proxy classes is defined here. Linear algebra operations ...
size_type size() const
Returns the length of the vector (cf. std::vector)
Definition: vector_def.hpp:118
All routines related to the Fast Fourier Transform. Experimental.
vcl_size_t size2() const
Returns the number of columns of the matrix.
Implementations of operations using vandermonde_matrix.
void prod_impl(const matrix_base< NumericT > &mat, const vector_base< NumericT > &vec, vector_base< NumericT > &result)
Carries out matrix-vector multiplication.
viennacl::backend::mem_handle & handle(T &obj)
Returns the generic memory handle of an object. Non-const version.
Definition: handle.hpp:41
vcl_size_t size1() const
Returns the number of rows of the matrix.
Implementation of the ViennaCL scalar class.
memory_types get_active_handle_id() const
Returns an ID for the currently active memory buffer. Other memory buffers might contain old or no da...
