VEC_$DAMIN                        Domain/OS                         VEC_$DAMIN


NAME
     vec_$damin - find the minimum absolute value in a double-precision vector

SYNOPSIS (C)
     #include <apollo/base.h>
     #include <apollo/vec.h>

     long int vec_$damin(
          double *start_vec,
          long int &length,
          double *result)

SYNOPSIS (Pascal)
     %include '/sys/ins/base.ins.pas';
     %include '/sys/ins/vec.ins.pas';

     function vec_$damin(
          in start_vec: univ vec_$double_vector;
          in length: integer32;
          out result: double): integer32;

SYNOPSIS (FORTRAN)
     %include '/sys/ins/base.ins.ftn'
     %include '/sys/ins/vec.ins.ftn'

           parameter (nvec = 10)

           real*8 start_vec(nvec), result
           integer*4 length, location

           location = vec_$damin(start_vec, length, result)

DESCRIPTION
     Vec_$damin searches through length elements of start_vec, places the
     smallest absolute-valued element in result, and returns the location of
     the element with the smallest absolute value. By contrast, vec_$drmin
     finds the element with smallest signed value.  In the case of a tie,
     vec_$damin returns the index of the first minimum value found.
     Vec_$damin differs from vec_$amin in that the argument vector is double-
     precision floating-point.


     start_vec
          The vector to be searched.

     length
          The number of elements to be operated on;  normally the same as the
          number of elements in the vectors.

     result
          The value of the smallest element in start_vec.

NOTES
     In C and Pascal, vec_$damin searches a row vector; in FORTRAN, it
     searches a column vector.
