Hi,
I have just signed up for the help forum. In running some of the
examples from the comm doc I have gotten the following :
1) Bose Chaudhuri Hocquenghem (BCH) block codes
octave:111> cdec = encode (bi2de (msg), n, k, "hamming/decimal")
error: fix: not defined for galois
error: called from
bi2de at line 60 column 3
octave:111>
2)
octave:113> pg = pgs(floor (rand () * (rows (pgs) + 1)),:)
error: pgs(0,_): subscripts must be either integers 1 to (2^31)1 or logicals
octave:113>
3)
gg = rsgenpoly (n, k, prim, b, s)
msg = gf (floor (2^m * rand (17, k)), m, prim);
noisy = code + [toeplitz([ones(1,17)], zeros(1,17)), zeros(17,238)];
warning: toeplitz: column wins diagonal conflict
arning: called from
toeplitz at line 80 column 7
[dec, nerr] = rsdec (msg, n, k, b, s)
error: rsdec: coded message contains incorrect number of symbols
