OpenCL kernel file for FFT operations.
Represents an OpenCL kernel within ViennaCL.
Definition: kernel.hpp:58
Various little tools used here and there in ViennaCL.
Main kernel class for generating OpenCL kernels for the fast Fourier transform.
Definition: fft.hpp:260
Manages an OpenCL context and provides the respective convenience functions for creating buffers...
Definition: context.hpp:55
This file provides the forward declarations for the main types used within ViennaCL.
vcl_size_t size1() const
Returns the number of rows of the matrix.
A Vandermonde matrix class.
Definition: forwards.h:418
Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
Definition: cpu_ram.hpp:34
viennacl::ocl::kernel & get_kernel(std::string const &program_name, std::string const &kernel_name)
Convenience function for retrieving the kernel of a program directly from the context.
Definition: context.hpp:605
Implementations of the OpenCL backend, where all contexts are stored in.
void enqueue(KernelType &k, viennacl::ocl::command_queue const &queue)
Enqueues a kernel in the provided queue.
Definition: enqueue.hpp:50
The vector type with operator-overloads and proxy classes is defined here. Linear algebra operations ...
All routines related to the Fast Fourier Transform. Experimental.
static void init(viennacl::ocl::context &ctx)
Definition: fft.hpp:267
Implementation of the ViennaCL scalar class.
void prod_impl(const matrix_base< NumericT > &A, bool trans_A, const vector_base< NumericT > &vec, vector_base< NumericT > &result)
Carries out matrix-vector multiplication.
