KryptologieA program for the WALSH transform |
|
The program reads from standard input and writes to standard output. The output was generated by the command line
wt < data.txt > result.txt
Input and output are in "natural order": The bit string u1u2u3u4 is represented by the integer 8u1 + 4u2 + 2u3 + u4.
cf(u1u2u3u4) = (-1)u1u2+u3u4
