Sparse matrix to dense matrix conversion. More...

Public Member Functions
integer(kind(rocsparse_status_success)) function	rocsparse_sparse_to_dense_ (handle, mat_A, mat_B, alg, buffer_size, temp_buffer)

Detailed Description

Sparse matrix to dense matrix conversion.

rocsparse_sparse_to_dense rocsparse_sparse_to_dense performs the conversion of a sparse matrix in CSR, CSC, or COO format to a dense matrix

Note

This function writes the required allocation size (in bytes) to buffer_size and returns without performing the sparse to dense operation, when a nullptr is passed for temp_buffer.

This function is non blocking and executed asynchronously with respect to the host. It may return before the actual computation has finished.

Parameters

[in]	handle	handle to the rocsparse library context queue.
[in]	mat_A	sparse matrix descriptor.
[in]	mat_B	dense matrix descriptor.
[in]	alg	algorithm for the sparse to dense computation.
[out]	buffer_size	number of bytes of the temporary storage buffer. buffer_size is set when temp_buffer is nullptr.
[in]	temp_buffer	temporary storage buffer allocated by the user. When a nullptr is passed, the required allocation size (in bytes) is written to buffer_size and function returns without performing the sparse to dense operation.

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_pointer	mat_A, mat_B, or buffer_size pointer is invalid.
