Procedure

     MINAI  ( Minimum element of array, integer )

     SUBROUTINE MINAI ( ARRAY, NDIM, MINVAL, LOC )

Abstract

     Locate the minimum element of an integer array.

Required_Reading

     None.

Keywords

     ARRAY
     SEARCH

Declarations

     IMPLICIT NONE

     INTEGER               ARRAY ( * )
     INTEGER               NDIM
     INTEGER               MINVAL
     INTEGER               LOC

Brief_I/O

     VARIABLE  I/O  DESCRIPTION
     --------  ---  -------------------------------------------------
     ARRAY      I   Array.
     NDIM       I   Number of elements in ARRAY.
     MINVAL     O   Minimum value in ARRAY.
     LOC        O   Location of MINVAL in ARRAY.

Detailed_Input

     ARRAY    is an arbitrary array.

     NDIM     is the number of elements in ARRAY.

Detailed_Output

     MINVAL   is the value in array that is less than or equal
              to all other values in the array. If the array
              contains more than one element with this value,
              the first one is returned.

     LOC      is the location of the minimum element. That is,
              MINVAL contains element ARRAY(LOC).

Parameters

     None.

Exceptions

     Error free.

     1)  If the array is empty (NDIM is less than one), LOC is zero,
         and MINVAL is not changed.

Files

     None.

Particulars

     None.

Examples

     Let array A contain the following elements.

        A(1) = 16
        A(2) =  4
        A(3) = 32
        A(4) = 64
        A(5) =  2
        A(6) =  8

     Then following the call

        CALL MINAI ( A, 6, MINVAL, LOC )

     the values of MINVAL and LOC are 2 and 5 respectively.

Restrictions

     None.
