NAME
vec_$iadd_vector - add two 32-bit integer vectors
SYNOPSIS (C)
#include <apollo/base.h>
#include <apollo/vec.h>
void vec_$iadd_vector(
long *start_vec,
long *add_vec,
long int &length,
long *result_vec)
SYNOPSIS (Pascal)
%include '/sys/ins/base.ins.pas';
%include '/sys/ins/vec.ins.pas';
procedure vec_$iadd_vector(
in start_vec: univ vec_$integer32_vector;
in add_vec: univ vec_$integer32_vector;
in length: integer32;
out result_vec: univ vec_$integer32_vector);
SYNOPSIS (FORTRAN)
%include '/sys/ins/base.ins.ftn'
%include '/sys/ins/vec.ins.ftn'
parameter (nvec = 10)
integer*4 start_vec(nvec), add_vec(nvec), result_vec(nvec)
integer*4 length
call vec_$iadd_vector(start_vec, add_vec, length, result_vec)
DESCRIPTION
Vec_$iadd_vector adds the 32-bit integer vectors start_vec and add_vec,
and supplies the vector sum in result_vec.
In C, the resulting operation is
for (i = 0; i < length; ++i)
result_vec[i] = start_vec[i] + add_vec[i];
In Pascal, the resulting operation is
for i := 1 to length do
begin
result_vec[i] := start_vec[i] + add_vec[i];
end
In FORTRAN, the resulting operation is
do 10 i = 1, length
result_vec(i) = start_vec(i) + add_vec(i)
10 continue
start_vec
An addend vector.
add_vec
An addend vector.
length
Number of elements to sum. Length is usually just the order of the
addends.
result_vec
The vector that is the sum of start_vec and add_vec.
NOTES
When vec_$iadd_vector is used to operate on matrixes in C and Pascal,
start_vec and result_vec are row vectors; whereas in FORTRAN, they are
column vectors.
