Problem 742. Symmetric matrix

Created by Aurelien Queffurust

You must create a n-by-n symmetric matrix such that A(row,col) = row/col for col >= row.

Example if n =3 :

output is : A =

      1.0000    0.5000    0.3333
      0.5000    1.0000    0.6667
      0.3333    0.6667    1.0000

since A(2,1) = A(1,2) = 1/2

or A(3,1)= A(1,3) = 1/3

Faulty solution that passes the test suite due to ill-defined test criterium in tests 3 and 4: obviously, the function output and A_correct are not the same.
