fn mult_tern(&self, b: &NtruTernPoly, mod_mask: u16) -> (NtruIntPoly, bool)

General polynomial by ternary polynomial multiplication

Multiplies a NtruIntPoly by a NtruTernPoly. The number of coefficients must be the same for both polynomials. It also returns if the number of coefficients differ or not.

General polynomial by ternary polynomial multiplication

Multiplies a NtruIntPoly by a NtruTernPoly. The number of coefficients must be the same for both polynomials. Uses 32-bit arithmetic. It also returns if the number of coefficients differ or not.

fn mult_tern_64(&self, b: &NtruTernPoly, mod_mask: u16) -> (NtruIntPoly, bool)

General polynomial by ternary polynomial multiplication

Multiplies a NtruIntPoly by a NtruTernPoly. The number of coefficients must be the same for both polynomials. Uses 64-bit arithmetic. It also returns if the number of coefficients differ or not.

fn mult_tern_sse(&self, b: &NtruTernPoly, mod_mask: u16) -> (NtruIntPoly, bool)

General polynomial by ternary polynomial multiplication, SSSE3 version

Multiplies a NtruIntPoly by a NtruTernPoly. The number of coefficients must be the same for both polynomials. This variant requires SSSE3 support. It also returns if the number of coefficients differ or not.

fn add_tern(&self, b: &NtruTernPoly) -> NtruIntPoly

fn mult_prod(&self, b: &NtruProdPoly, mod_mask: u16) -> (NtruIntPoly, bool)

General polynomial by product-form polynomial multiplication
