Shape(/5,5/) and scalar ra = rb + rc*id ! Shape(/3,2/) ra(3:5,3:4) = rb(1::2,3:5:2) + rc(1:3,1:2) ! 7 Recursion It is important to be aware of how to achieve recursion in Fortran 90: For example, the code: DO i=2,n x(i) = x(i) + x(i-1) END DO is not the same as: x(2:n)= x(2:n) + x(1:n-1) In the first case, the assignment is: x(i) = x(i) + x(i-1) + x(i-2) + ... + x(1) whereas in the second case the assignment is: x(i) = x(i) + x(i-1) In order to achieve the recursive effect of the DO-loop, in Fortran 90 it would be appropriate to use the intrinsic function SUM.

Find the maximum value less than 1000 in this array. In Fortran 77 this requires triple DO loop and IF statements, whereas the Fortran 90 code is: REAL, DIMENSION(10,10,10) :: a amax=MAXVAL(a,MASK=(a<1000)) Note the use of the optional MASK argument. MASK is a logical array expression. Only those elements of a that correspond to elements of MASK that have the value true take part in the function call. So in this example amax is the value of the maximum element in a which is less than 1000. 4. Find the average value greater than 3000 in an array.
