Wow--numerical code that I can actually read! This looks awesome.

I suppose that it would not be hard to adapt the code to use the
vector and matrix declarations in the Annex G.3 part of Ada 2005, e.g.

type Real_Vector is array (Integer range <>) of Real'Base;
type Real_Matrix is array (Integer range <>, Integer range <>)
                                                   of Real'Base;

replacing the scattered declarations such as

type Data_Array is array (Array_Index) of Real;
type A_Matrix is array(R_Index, C_Index) of Real;

I really like the "standardized" way of these Ada 2005 declarations.
