Example code from Wikipedia:

C     Multiply vector by matrix
      REAL M(,), V(), R()
      R = SUM(M*MATR(A))

C     Converge to a Laplace potential in an area
      REAL P(,), OLD_P(,)
      LOGICAL INSIDE(,)
      DO 1 K = 1, ITERATIONS
      OLD_P = P
      P(INSIDE) = 0.25*(P(,+)+P(,-)+P(+,)+P(-,))
      IF (MAX(ABS(P-OLD_P)) .LT. EPS) RETURN
    1 CONTINUE
