That's excellent advice.

But if you can't do that, and it really is important to ensure
complete initialization, and you are completing run-time check proofs,
then you could force a check on the array:

--# check for all I in Natural range Out_Matrix'Range(1) =>
--#         (for J in Natural range Out_Matrix'Range(2) =>
--#             (Out_Matrix(I, J) in Types.Float8));

but, for a complex initialization, completing the proof of this check
will be correspondingly complex :-(

Cheers,
