The user provides the input data and is responsible for destroying
this data after matrix J has been destroyed.
The operation <A HREF="../Mat/MatMult.html#MatMult">MatMult</A>(A,D2,D1) must be well defined.
Before calling the operation <A HREF="../Mat/MatGetDiagonal.html#MatGetDiagonal">MatGetDiagonal</A>(), the function
MatADAComputeDiagonal() must be called. The matrices A and D1 must
be the same during calls to MatADAComputeDiagonal() and
<A HREF="../Mat/MatGetDiagonal.html#MatGetDiagonal">MatGetDiagonal</A>().
