title: Printing 2D matrix on Fortran 90
body: <p>I am trying to print a 2D matrix of real numbers using fortran 90 using format descriptor F, and it keeps being printed as a single column. what should I do?
  My code:</p>
  <pre><code>do i=1,N
     do j=1,M
        A(i,j) = 2.4
     end do
  end do
  write(*,'(F6.2)')((A(i,j), j=1,M), i=1,N)
  </code></pre>
