Abstract

The description of a special single-purpose relay machine for automatic series evaluation of the functions cos (2π/1024)(hx+ky+lz) and sin (2π/1024)(hx+ky+lz) and its utilization for calculating structure factor components is expressed by

$$A_{hkl} = \sum\limits_j {f_j \cos \frac{{2\pi }}{{1024}}(hx_j + ky_j + lz_j )} $$

and

$$B_{hkl} = \sum\limits_j {f_j \sin \frac{{2\pi }}{{1024}}(hx_j + ky_j + lz_j ).} $$
