What the program does in this section is multiply the diagonal of the matrix by
2 with the line -
tt=tt+tt
and so (0.8000E+01 -> 0.1600E+02), (0.1000E+02 -> 0.2000E+02) and (0.1300E+02
-> 0.2600E+02 ) and the other three elememts should stay the same. In debug
mode, most compilers will give the correct answer, but the addition is
sometimes being optmized away.
