polyvecdecompress function
Decompresses a polyvec from bytes using polydecompress on each polynomial.
Implementation
PolyVec polyvecdecompress(Uint8List r) {
PolyVec v = PolyVec();
for (int i = 0; i < KYBER_K; i++) {
v.vec[i] = polydecompress(r.sublist(
i * KYBER_POLYCOMPRESSEDBYTES, (i + 1) * KYBER_POLYCOMPRESSEDBYTES));
}
return v;
}
