integer(kind(rocsparse_status_success)) function	rocsparse_scatter_ (handle, x, y)

Scatter elements from a sparse vector into a dense vector.

rocsparse_scatter scatters the elements from the sparse vector \(x\) in the dense vector \(y\).

for(i = 0; i < nnz; ++i)
{
    y[x_ind[i]] = x_val[i];
}

Note: 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]	x	sparse vector \(x\).
[out]	y	dense vector \(y\).

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_pointer	`x` or `y` pointer is invalid.

integer(kind(rocsparse_status_success)) function hipfort_rocsparse::rocsparse_scatter::rocsparse_scatter_	(	type(c_ptr), value	handle,
		type(c_ptr), value	x,
		type(c_ptr), value	y
	)
