Struct SparseVector 

pub struct SparseVector {
    pub data: Vec<f64>,
}

Thin wrapper around Vecf64` for sparse/dense vector operations.

Fields

data: Vec<f64>

The underlying dense data.

Implementations

impl SparseVector

pub fn new(len: usize) -> Self

Create a new zero vector of the given length.

pub fn from_vec(data: Vec<f64>) -> Self

Create a sparse vector from existing data.

pub fn len(&self) -> usize

Return the length of the vector.

pub fn is_empty(&self) -> bool

Check if the vector is empty.

pub fn dot(&self, other: &Self) -> f64

Compute the dot product with another vector.

pub fn norm(&self) -> f64

Compute the Euclidean norm.

pub fn axpby(&mut self, alpha: f64, other: &SparseVector, beta: f64)

AXPY: self = alpha * self + beta * other

pub fn scale(&mut self, alpha: f64)

Scale all entries by a scalar.
