MatDenseGetArrayWriteAndMemType#

gives write-only access to the array where the data for a MATDENSE matrix is stored

Synopsis#

Logically Collective

Input Parameter#

  • A - a dense matrix

Output Parameters#

  • array - pointer to the data

  • mtype - memory type of the returned pointer

Note#

If the matrix is of a device type such as MATDENSECUDA, MATDENSEHIP, etc., an array on device is always returned and is guaranteed to contain the matrix’s latest data.
