The first step in using the Ginkgo library consists of creating an executor.
Definition executor.hpp:616
Definition lin_op.hpp:118
A LinOp implementing this interface can write its data to a matrix_data structure.
Definition lin_op.hpp:661
An array is a container which encapsulates fixed-sized arrays, stored on the Executor tied to the arr...
Definition array.hpp:167
value_type * get_data() noexcept
Returns a pointer to the block of memory used to store the elements of the array.
Definition array.hpp:674
const value_type * get_const_data() const noexcept
Returns a constant pointer to the block of memory used to store the elements of the array.
Definition array.hpp:683
Permutation is a matrix format that represents a permutation matrix, i.e.
Definition permutation.hpp:113
static std::unique_ptr< Permutation > create(std::shared_ptr< const Executor > exec, size_type size=0)
Creates an uninitialized Permutation arrays on the specified executor.
size_type get_permutation_size() const noexcept
Returns the number of elements explicitly stored in the permutation array.
std::unique_ptr< Permutation > compose(ptr_param< const Permutation > other) const
Composes this permutation with another permutation.
index_type * get_permutation() noexcept
Returns a pointer to the array of permutation.
Definition permutation.hpp:126
static std::unique_ptr< const Permutation > create_const(std::shared_ptr< const Executor > exec, size_type size, gko::detail::const_array_view< IndexType > &&perm_idxs, mask_type enabled_permute=row_permute)
Creates a constant (immutable) Permutation matrix from a constant array.
const index_type * get_const_permutation() const noexcept
Returns a pointer to the array of permutation.
Definition permutation.hpp:135
std::unique_ptr< Permutation > compute_inverse() const
Returns the inverse permutation.
This class is used for function parameters in the place of raw pointers.
Definition utils_helper.hpp:43
permute_mode operator|(permute_mode a, permute_mode b)
Combines two permutation modes.
permute_mode operator&(permute_mode a, permute_mode b)
Computes the intersection of two permutation modes.
permute_mode operator^(permute_mode a, permute_mode b)
Computes the symmetric difference of two permutation modes.
std::ostream & operator<<(std::ostream &stream, permute_mode mode)
Prints a permutation mode.
permute_mode
Specifies how a permutation will be applied to a matrix.
Definition permutation.hpp:43
@ none
Neither rows nor columns will be permuted.
