Struct Matrix 

pub struct Matrix { /* private fields */ }

Represents a matrix of field elements, of arbitrary dimensions

This is in row major order, so consider processing elements in the same row first, for locality.

Implementations

impl Matrix

pub fn init(rows: usize, cols: usize, data: impl Iterator<Item = F>) -> Self

Initialize a matrix, with dimensions, and data to pull from.

Any extra data is ignored, any data not supplied is treated as 0.

pub fn as_polynomials( &self, min_coefficients: usize, ) -> Option<PolynomialVector>

Interpret the columns of this matrix as polynomials, with at least min_coefficients.

This will, in fact, produce a matrix padded to the next power of 2 of that number.

This will return None if min_coefficients < self.rows, which would mean discarding data, instead of padding it.

pub fn mul(&self, other: &Self) -> Self

Multiply this matrix by another.

This assumes that the number of columns in this matrix match the number of rows in the other matrix.

pub const fn rows(&self) -> usize

pub const fn cols(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = &[F]>

pub fn rand(rng: impl CryptoRngCore, rows: usize, cols: usize) -> Self

Create a random matrix with certain dimensions.

Trait Implementations

impl Clone for Matrix

fn clone(&self) -> Matrix

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Matrix

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl EncodeSize for Matrix

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

impl Index<(usize, usize)> for Matrix

type Output = F

The returned type after indexing.

fn index(&self, (i, j): (usize, usize)) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Index<usize> for Matrix

type Output = [F]

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<(usize, usize)> for Matrix

fn index_mut(&mut self, (i, j): (usize, usize)) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl IndexMut<usize> for Matrix

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Matrix

fn eq(&self, other: &Matrix) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Read for Matrix

type Cfg = usize

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, max_els: &Self::Cfg) -> Result<Self, Error>

Reads a value from the buffer using the provided configuration cfg.

impl Write for Matrix

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.
