eval_fast_rotation_precompute: Precompute digit decomposition for hoisted fast rotations

eval_fast_rotation_precomputeR Documentation

Precompute digit decomposition for hoisted fast rotations

Description

Computes the digit decomposition of a ciphertext once so that multiple eval_fast_rotation() calls against the same ciphertext avoid redoing it. The cyclotomic order m (typically 2 * N, where N is the ring dimension) is required by eval_fast_rotation().

Usage

eval_fast_rotation_precompute(ct, ...)

Arguments

ct

A Ciphertext

...

Reserved for future method-specific arguments

Value

A FastRotationPrecomputation
