VEC_$DRMIN                        Domain/OS                         VEC_$DRMIN


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

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

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

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

     function vec_$drmin(
          in start_vec: univ vec_$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_$drmin(start_vec, length, result)

DESCRIPTION
     Vec_$drmin searches through length elements of start_vec, sets result to
     the smallest value in the vector, and returns the location of the element
     with the smallest value. By contrast, vec_$damin finds the element with
     smallest absolute value.  In the case of a tie, vec_$drmin returns the
     index of the first minimum value found.


     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_$drmin searches a row vector; in FORTRAN, it
     searches a column vector.
