The coefficient matrices are compressed by truncation with a prescribed threshold value \u03ba. The value of \u03ba is determined so that the amount of storage is minimized without reducing the accuracy of BE solution, and shows \u03ba \u2248 \u03c1N\u2212\u03b2 (\u03c1, \u03b2 \u003e 0). The number of non-zero entries of the matrices G and H, (G) and (H) increases in proportion to O(N log N) or O(N1+\u03b3) (0 \u003c \u03b3 \u003c 1).
