There is a technical reason for this, which appears in Pascal, where

   type Matrix is array [1 .. n, 1 .. m] of Real;

is defined as equivalent to

   type Matrix is array [1 .. n] of array [1 .. m] of Real;

so it is quite natural to chose an ordering different from FORTRAN.

BTW the above is not true in Ada, and the layout of arrays in memory is
not sepcified by the language.
