The types from Ada.Numerics are convention Ada by default, while the
types in Ada_Lapack are convention Fortran.
It would be nice to be able to say something like
with Ada.Numerics.Generic_Complex_Arrays;
generic
with package Complex_Arrays
is new Ada.Numerics.Generic_Complex_Arrays (<>);
package Conventions is
type Complex_Matrix
is new Complex_Arrays.Complex_Matrix with Convention => Fortran;
which would give you the operations you want, but unfortunately
gcc -c -gnat12 conventions.ads
conventions.ads:9:46: representation item appears too late
conventions.ads:9:46: primitive operations already defined for "Complex_Matrix"
gnatmake: "conventions.ads" compilation error

Who are these "Ada programmers"? Looks to me as though it's you, Leo and
Nasser!
