Enumeration Type Documentation

◆ DimensionSelectionType

enum class tatami::DimensionSelectionType : char

strong

Selection of dimension elements:

FULL: selects the full extent of the dimension, i.e., all elements.
BLOCK: selects a contiguous block of elements in the dimension.
INDEX: selects a sorted and unique array of indices of dimension elements.

This corresponds to the various overloads of Matrix methods (e.g., Matrix::dense_row()), each of which extracts a different selection of elements from the non-target dimension.

◆ ArithmeticOperation

enum class tatami::ArithmeticOperation : char

strong

Type of arithmetic operation.

The INTEGER_DIVIDE refers to a floored division, which differs from truncation for negative quotients. This choice is based on R's %/%, which in turn is based on a recommendation by Donald Knuth.

Similarly, x MODULO y is defined as x - floor(x / y), based on the same floored division. Note that this differs from the built-in % operator, which performs truncation.

◆ BooleanOperation

enum class tatami::BooleanOperation : char

strong

Type of boolean operation.

◆ CompareOperation

enum class tatami::CompareOperation : char

strong

Type of comparison operation.

◆ SpecialCompareOperation

enum class tatami::SpecialCompareOperation : char

strong

Type of comparison operation for special IEEE values.

◆ SomeNumericType

enum tatami::SomeNumericType

Types supported in SomeNumericArray. The letters indicate whether it is an integer (I), unsigned integer (U) or a float, while the numbers specify the number of bits for the type. So, for example, U16 is an unsigned 16-bit integer, while F64 is a double.

◆ transpose() [1/2]

template<typename Input_ , typename Output_ >

void tatami::transpose	(	const Input_ *	input,
		size_t	nrow,
		size_t	ncol,
		size_t	input_stride,
		Output_ *	output,
		size_t	output_stride )

Template Parameters

Input_	Input type.
Output_	Output type.

Parameters

[in]	input	Pointer to an array containing a row-major matrix with `nrow` rows and `ncol` columns. Elements within each row should be contiguous but consecutive rows can be separated by a constant stride, see `input_stride`. The array should have at least `(nrow - 1) * input_stride + ncol` addressable elements.
	nrow	Number of rows in the matrix stored at `input`.
	ncol	Number of columns in the matrix stored at `input`.
	input_stride	Distance between corresponding entries on consecutive rows of the `input` matrix. This should be greater than or equal to `ncol`.
[out]	output	Pointer to an array in which to store the transpose of the matrix in `input`. On output, this stores a row-major matrix with `ncol` rows and `nrow` columns. Elements within each row should be contiguous but consecutive rows can be separated by a constant stride, see `output_stride`. The array should have at least `(ncol - 1) * output_stride + nrow` addressable elements. It is assumed that `output` does not alias `input`.
	output_stride	Distance between corresponding entries on consecutive rows of the `output` matrix. This should be greater than or equal to `nrow`.

This function is intended for developers of Matrix subclasses who need to do some transposition, e.g., for dense chunks during caching. The *_stride arguments allow input and output to refer to submatrices of larger arrays.

The argument descriptions refer to row-major matrices only for the sake of convenience. This function is equally applicable to column-major matrices, just replace all instances of "row" with "column" and vice versa.

◆ transpose() [2/2]

template<typename Input_ , typename Output_ >

void tatami::transpose	(	const Input_ *	input,
		size_t	nrow,
		size_t	ncol,
		Output_ *	output )

Template Parameters

Input_	Input type.
Output_	Output type.

Parameters

[in]	input	Pointer to an array containing a row-major matrix with `nrow` rows and `ncol` columns. The array should have at least `nrow * ncol` addressable elements, and all elements should be stored contiguously in the array.
	nrow	Number of rows in the matrix stored at `input`.
	ncol	Number of columns in the matrix stored at `input`.
[out]	output	Pointer to an array of length `nrow * ncol`. On output, this will hold the transpose of the matrix represented by `input`, i.e., a row-major matrix with `ncol` rows and `nrow` columns. It is assumed that `output` does not alias `input`.

This function is intended for developers of Matrix subclasses who need to do some transposition, e.g., for dense chunks during caching. Users should instead construct a DelayedTranspose object to perform a memory-efficient delayed transposition, or use convert_to_dense() to convert their dense data into the desired storage layout.

The argument descriptions refer to row-major matrices only for the sake of convenience. This function is equally applicable to column-major matrices, just replace all instances of "row" with "column" and vice versa.

◆ make_DelayedCast()

		ColumnIndices_ &	column_indices,
		bool	csr )

Template Parameters

ColumnIndices_	Random access container for the column indices.

Parameters

nrow	Number of rows.

values	Values of the structural non-zeros. This must be of the same length as `row_indices` and `column_indices`, where corresponding entries contain data for a single structural non-zero.
csr	Whether to create a compressed sparse row format. If `false`, the compressed sparse column format is used instead.

Returns: row_indices, column_indices and values are sorted in-place by the row and column indices (if csr = true) or by the column and row indices (if csr = false). A vector of index pointers is returned with length nrow + 1 (if csr = true) or ncol + 1 (if csr = false).

◆ count_compressed_sparse_non_zeros()

template<typename Value_ , typename Index_ , typename Count_ >

void tatami::count_compressed_sparse_non_zeros	(	const tatami::Matrix< Value_, Index_ > &	matrix,

	options	Further options.

For sparse matrix, all structural non-zero elements are reported, even if they have actual values of zero. In contrast, for dense matrix, only the non-zero values are counted; these are considered to be structural non-zeros upon conversion to a sparse matrix (e.g., in fill_compressed_sparse_contents()).

◆ fill_compressed_sparse_contents()

template<typename InputValue_ , typename InputIndex_ , typename Pointer_ , typename StoredValue_ , typename StoredIndex_ >

Each entry contains the position of the start of each row/column in `output_value` and `output_index`. This argument is equivalent to the array of pointers for the compressed sparse format (e.g., `CompressedSparseContents::pointers`), and can be obtained by taking the cumulative sum of the per-row/column counts from `count_compressed_sparse_non_zeros()`.
[out]	output_value	Pointer to an array of length equal to the total number of structural non-zero elements. On output, this is used to store the values of those elements in a compressed sparse format (e.g., `CompressedSparseContents::value`).
[out]	output_index	Pointer to an array of length equal to the total number of structural non-zero elements. On output, this is used to store the row/column indices of those elements in a compressed sparse format (e.g., `CompressedSparseContents::index`).
	options	Further options.

Apply a function to a set of tasks in parallel, usually for iterating over a dimension of a Matrix. By default, this uses subpar::parallelize_range() internally, which uses OpenMP if available and <thread> otherwise. Advanced users can override the default parallelization mechanism by defining a TATAMI_CUSTOM_PARALLEL function-like macro. The macro should accept the fun, tasks and threads arguments as described below.

Template Parameters

parallel_	Whether the tasks should be run in parallel. If `false`, no parallelization is performed and all tasks are run on the current thread.
Function_	Function to be applied for a contiguous range of tasks. This should accept three arguments: `thread`, the thread number executing this task range. This will be passed as a `size_t`. `task_start`, the start index of the task range. This will be passed as a `Index_`. `task_length`, the number of tasks in the task range. This will be passed as a `Index_`.
Index_	Integer type for the number of tasks.

Parameters

fun	Function that executes a contiguous range of tasks.
tasks	Number of tasks.
threads	Number of threads.

◆ process_consecutive_indices()

template<typename Index_ , class Function_ >

void tatami::process_consecutive_indices	(	const Index_ *	indices,
		Index_	length,
		Function_	fun )

Process runs of consecutive indices that are used in the index-aware dense_row(), sparse_column(), etc. methods. This provides some opportunities for optimization when the indices contain contiguous stretches. For example, third-party libraries can be asked to process blocks of observations rather than handling them one at a time.

Template Parameters

Index_	Integer type for the row/column indices.
Function_	Function to apply to each contiguous run.

Parameters

indices	Pointer to an array of sorted and unique indices for row/column elements.
length	Length of the array pointed to by `indices`.
fun	Function to apply to each contiguous run of indices. This should take two arguments - the start index of each run, and the length of the run. Calls to `fun` are guaranteed to contain increasing start indices with non-overlapping runs. The return value of this function is ignored.

◆ wrap_shared_ptr()

template<typename Value_ , typename Index_ >

std::shared_ptr< const Matrix< Value_, Index_ > > tatami::wrap_shared_ptr ( const Matrix< Value_, Index_ > * ptr )

Wrap a raw pointer inside a shared_ptr, typically to enable use of a raw tatami::Matrix pointer with delayed operation wrappers. This enables use of delayed operations inside functions that accept a raw pointer to an externally owned tatami::Matrix.

Template Parameters

Value_	Numeric type for the matrix value.
Index_	Integer type for the row/column indices.

Parameters

ptr	A pointer to a `tatami::Matrix` instance.

Returns: A shared pointer to the same object addressed by ptr. The assumption is that ptr will always outlive the returned pointer.
