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

Detailed Description

Scatter elements from a sparse vector into a dense vector.

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

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

rocsparse_scatter supports the following uniform-precision data types for the sparse and dense vectors x and y.

Uniform Precisions:

X / Y
rocsparse_datatype_i8_r
rocsparse_datatype_f16_r
rocsparse_datatype_bf16_r
rocsparse_datatype_f32_r

Note
This function is non-blocking and executed asynchronously with respect to the host. It can return before the actual computation has finished.
This routine supports execution in a hipGraph context.
This routine does not support batched computation.
Parameters
[in]handle- handle to the rocSPARSE library context queue.
[in]x- sparse vector \(x\).
[out]y- dense vector \(y\).
Return values
rocsparse_status_successthe operation completed successfully.
rocsparse_status_invalid_handlethe library context was not initialized.
rocsparse_status_invalid_pointerx or y pointer is invalid.
