I'm surprised nobody has jumped in on this but...
To represent a 2-D matrix, the best type to use is probably
a discriminated record.  Something like:

type  elements_2 is array(positive range <>, positive range <>) of integer;
type matrix_2 (rows: positive; columns: positive) is
   record
      data : elements_2 (1..rows, 1..columns);
   end record;

   obj: matrix_2 (2,3) := (2,3, ((1,2), (3,6), (77,89)));
   ...
