MatDenseHIPRestoreArrayRead#
Restore read-only access to the HIP buffer inside a dense matrix previously obtained with a call to MatDenseHIPGetArrayRead().
Synopsis#
#include "petscmat.h"
PetscErrorCode MatDenseHIPRestoreArrayRead(Mat A, const PetscScalar **a)
Not Collective
Input Parameters#
A - the matrix
array - the GPU array in column major order
Notes#
Data can be copied to the GPU due to operations done on the CPU. If you need write only access, use MatDenseHIPGetArrayWrite().
