MatDenseGetArrayReadAndMemType#
gives read-only access to the array where the data for a MATDENSE
matrix is stored
Synopsis#
#include "petscmat.h"
PetscErrorCode MatDenseGetArrayReadAndMemType(Mat A, const PetscScalar **array, PetscMemType *mtype)
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.
