Solution

• MAXLOC((/2,7,3,5,9,1/)) = (/ 5 /)
• MAXVAL((/2,7,3,5,9,1/)) = 9
• MAX( (/2,7,3,5,9,1/),(/1,9,5,3,7,2/)) = (/2,9,5,5,9,2/)
• MINLOC((/2,7,3,5,9,1/)) = (/ 6 /)
• MINVAL((/2,7,3,5,9,1/)) = 1
• MIN( (/2,7,3,5,9,1/),(/1,9,5,3,7,2/)) = (/1,7,3,3,7,1/)

And:

• MAXLOC(A, MASK = A .LT. 5) = (/ 2, 2 /)
• MAXVAL(A, MASK = A .LT. 5) = 4
• MAXLOC(A, MASK = A .LT. 4) = (/ 2, 1 /) -- first location
• MAXVAL(A, MASK = A .LT. 4) = 3
