Input Parameters#

  • A - the matrix

Output Parameters

  • array - the GPU array in column major order

Notes#

The data on the GPU may not be updated due to operations done on the CPU. If you need updated data, use MatDenseHIPGetArray(). The array must be restored with MatDenseHIPRestoreArrayWrite() when no longer needed.
