integer(kind(rocsparse_status_success)) function | rocsparse_gather_ (handle, y, x) |
Detailed Description
Gather elements from a dense vector and store them into a sparse vector.
rocsparse_gather
gathers the elements from the dense vector \(y\) and stores them in the sparse vector \(x\).
for(i = 0; i < nnz; ++i)
{
x_val[i] = y[x_ind[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] y dense vector \(y\). [out] x sparse vector \(x\).
- Return values
-
rocsparse_status_success the operation completed successfully. rocsparse_status_invalid_handle the library context was not initialized. rocsparse_status_invalid_pointer x
ory
pointer is invalid.
