pub fn simple_bit_unpack(data: &[u8], b: u32, w: &mut [i32; 256])Expand description
Unpack a polynomial whose coefficients lie in [0, b].
Implements Algorithm 18 of FIPS 204 (SimpleBitUnpack). Inverse of
simple_bit_pack.
data: packed byte data.b: upper bound on coefficient values.w: output polynomial (filled with decoded coefficients).
