Hi, Steven, MatSetSeqAIJKokkosWithCSRMatrix(Mat A, Mat_SeqAIJKokkos *akok) uses a private data type Mat_SeqAIJKokkos, so it can not be directly made public. If you already use COO, then why not directly make the matrix of type MATAIJKOKKOS and call MatSetPreallocationCOO() and MatSetValuesCOO()? So I am confused by your needs.
