MatDenseGetArrayAndMemType#

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

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatDenseGetArrayAndMemType(Mat A, PetscScalar **array, PetscMemType *mtype)

Logically Collective

Input Parameter#

  • mat - a dense matrix

Output Parameters#

  • array - pointer to the data

  • mtype - memory type of the returned pointer

Notes#

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.
