ob-fortran behaviour

[Christopher Dimech <dimech@gmx.com>]

Fortran is behaving in a weird way

  #+BEGIN_SRC fortran
    program matrx_vectr_mult
    implicit none

    integer :: m, n, i, j, k
    real :: a(5,3), u(3), v(5), rsum

    m = 5;  n = 3
    a = 0.0;  u = 0.0;  v = 0.0

    k = 0
    do j = 1, n
      do i = 1, m
        k = i + j
        a(i,j) = real(k)
        u(i) = real(3*i)
      end do
    end do

    do i = 1, m
      rsum = 0.0
      do j = 1, n
        rsum = (a(i,j) * u(j)) + rsum
      end do
      v(i) = rsum
    end do

    write (*,*) "a * *", " * ", "u", " * ", "v"
    write (*,*) a(1,:), "*", u(1), "*", v(1)
    write (*,*) a(2,:), "*", u(2), "*", v(2)
    write (*,*) a(3,:), "*", u(3), "*", v(3)
    write (*,*) a(4,:), "* * *", v(4)
    write (*,*) a(5,:), "* * *", v(5)

    print *, "---"
    write (*,*) a

  end program
#+END_SRC
