Detailed Description

Function Documentation

std::pair<std::unique_ptr<column>, table_view> cudf::transpose	(	table_view const &	input,
		rmm::cuda_stream_view	stream = `cudf::get_default_stream()`,
		rmm::device_async_resource_ref	mr = `cudf::get_current_device_resource_ref()`
	)

Transposes a table.

Stores output in a contiguous column, exposing the transposed table as a table_view.

Exceptions

cudf::logic_error	if column types are non-homogeneous
cudf::logic_error	if column types are non-fixed-width

Parameters

[in]	input	A table (M cols x N rows) to be transposed
[in]	stream	CUDA stream used for device memory operations and kernel launches
[in]	mr	Device memory resource used to allocate the device memory of returned value

Returns: The transposed input (N cols x M rows) as a column and table_view, representing the owner and transposed table, respectively.
