A trait for engines performing (discarding) affine transformation of LWE ciphertexts.

Semantics

This discarding operation fills the output LWE ciphertext with the result of the affine tranform of the inputs LWE ciphertext vector, with the weights cleartext vector and the bias plaintext.

Formal Definition
