can give you different results beyond machine precision. There is also no
point to compare fortran and matlab results beyond machine precision.
And pi in matlab is not same as the pi you specified in your code.
As I said before, your code sucks, not fortran or matlab.

your Pi value is not accrate enough. Change it to
mypi=4.q0*atan(1.q0)
and see if it makes any difference. | g******s
