[Trilinos-Users] RCP<Epetra_MultiVector> convertion

[Bartlett, Roscoe A.]

Darn, I missed that.  Epetra is zero-based, not one-based.

Hello Antonella,

Try grabbing the first (and only) vector of your multivector using ()

http://trilinos.org/docs/r11.12/packages/epetra/doc/html/classEpetra__MultiVector.html#a9ff1873a78c6fecf7a3188f925689e9c

i.e. Epetra_Vector* x = (*X)(0);

We have a Teuchos::RCP<Epetra_MultiVector> X made of only 1 column,
and we want to convert this vector into a simple Epetra_Vector.
We used the following functions:

      const Teuchos::RCP<Epetra_Vector> x_rcp =
        Teuchos::rcpWithEmbeddedObj( (*X)(1), X, false );

      Epetra_Vector* x = x_rcp.getRawPtr();
We can compile these functions, but when we try to print out both
x_rcp and x we do not get any result (files are not written), the code stops
with error: terminate called after throwing an instance of 'int'.
What are we doing wrong?
