Struct SubMatrixRowSlices

pub struct SubMatrixRowSlices<M: Matrix<T>, T: Send + Sync> { /* private fields */ }

A submatrix of a matrix. The matrix will contain a subset of the columns of self.inner.

fn vertically_packed_row<P>(&self, r: usize) -> impl Iterator<Item = P>

where T: Copy, P: PackedValue<Value = T>,

Pack together a collection of adjacent rows from the matrix.

fn vertically_packed_row_pair<P>(&self, r: usize, step: usize) -> Vec<P>

where T: Copy, P: PackedValue<Value = T>,

Pack together a collection of rows and “next” rows from the matrix.

where Self: Sized,

fn columnwise_dot_product<EF>(&self, v: &[EF]) -> Vec<EF>

where T: Field, EF: ExtensionField<T>,

Compute Mᵀv, aka premultiply this matrix by the given vector, aka scale each row by the corresponding entry in v and take the sum across rows. v can be a vector of extension elements.

fn dot_ext_powers<EF>(&self, base: EF) -> impl IndexedParallelIterator

where T: Field, EF: ExtensionField<T>,

Multiply this matrix by the vector of powers of base, which is an extension element.
