Synopsis

PetscErrorCode MatDenseHIPRestoreArrayRead(Mat A, const PetscScalar **a)

Not Collective

Input Parameters

• A - the matrix

• a - the GPU array in column major order

Note

Data can be copied to the GPU due to operations done on the CPU. If you need write only access, use MatDenseHIPGetArrayWrite().
