distance | - pairwise distance matrix | |
pc_vector | - OUT compression descriptor vector
pc_vector[] format: each element (pc_vector[i]) describes the plain compression: first 3 bits - compression code: 0 - plain uncompressed 1 - plain is ALL ZERO (000000...) 2 - plain is ALL ONE (111111...) 3 - plain is equal to another plain J (5 high bits (max 31)) 4 - plain is close (but not equal) to plain J next 5 bits - number of plain used as a XOR expression ( compression codes: 3,4 ) |
