MAXLOC: Location of Maximum Value in an Array

The MAXLOC function finds the linear maximum value element position of an array, while MAX finds the maximum value.

• MAXLOC returns the
  maximum_value_location
  of the
  • scalar arguments or the array argument:
    • • result = MAXLOC( x, y, z, ...) ! x, y, z are numeric scalars, e.g.:
      • largest_loc = MAXLOC( 4, -3.1, EXP(1) ) ! sets largest_loc to 1
    • • REAL :: vec(5)
      • vec = RAN( 100, 10) ! e.g. 96.00351636 90.99435447 108.1637875 91.95317195 90.80626762
      • result = MAXLOC(vec) ! set to 3
  • a character string:
    • MAXLOC("Hello World") ! returns 9 == position of "r"
• MAX is to find the maximum value , e.g.:
  • value = MAX( vec ) ! is set to 108.1637875
• analogous functions are MIN and MINLOC
