I am trying to copy the soution x back to the application following the MAGMA example_sparse.c

Code: Select all

```
Foam::scalarField &solution; // solution vector of the application
// copy MAGMA solution and back to the application code
magma_dvget( x, n, 1, solution, queue );
```

Code: Select all

```
mGMRES_solve.C:98:38: error: invalid conversion from ‘int’ to ‘magma_int_t* {aka int*}’ [-fpermissive]
magma_dvget( x, n, 1, solution, queue );
^
mGMRES_solve.C:98:38: error: invalid conversion from ‘int’ to ‘magma_int_t* {aka int*}’ [-fpermissive]
mGMRES_solve.C:98:38: error: cannot convert ‘Foam::scalarField {aka Foam::Field<double>}’ to ‘double**’ for argument ‘4’ to ‘magma_int_t magma_dvget(magma_d_matrix, magma_int_t*, magma_int_t*, double**, magma_queue_t)’
```

Does anyone see my error?

Code: Select all

` magma_dvget( x, n, 1, solution, queue ); // n = vector size; x = MAGMA solution vector`
