VEC_$IASUM_I                      Domain/OS                       VEC_$IASUM_I


NAME
     vec_$iasum_i - sum the absolute value of the elements of a 32-bit integer
     vector

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

     long int vec_$iasum_i(
          long int *vector,
          long int &vec_inc,
          long int &length)

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

     function vec_$iasum_i(
          in vector: univ vec_$integer32_vector;
          in vec_inc: integer32;
          in length: integer32): integer32;

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

           parameter (nvec = 10)

           integer*4 vector(nvec), sum
           integer*4 length, vec_inc

           sum = vec_$iasum_i(vector, vec_inc, length)

DESCRIPTION
     Vec_$iasum_i adds together the absolute value of length elements of the
     32-bit integer array vector and returns the sum.

     This call, like all vec_$ calls ending in _i, takes a set of extra stride
     arguments, one for every vector argument.  The stride arguments determine
     which elements in the array are actually processed.  For instance, if the
     stride for a particular array is set to 3, every third element in the
     array will be processed by the routine.  The stride arguments need not be
     identical.  If all stride arguments are set to 1, this call behaves
     exactly like the version without the _i in its name.

     vector
          The vector to be summed.

     vec_inc
          The stride for vector.

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

NOTES
     When vec_$iasum_i is used to operate on matrixes in C and Pascal, vector
     is a row vector; in FORTRAN, it is a column vector.
