Struct forust_ml::data::RowMajorMatrix

pub struct RowMajorMatrix<T> {
    pub data: Vec<T>,
    pub rows: usize,
    pub cols: usize,
    /* private fields */
}

A lightweight row major matrix, this is primarily for returning data to the user, it is especially suited for appending rows to, such as when building up a matrix of data to return to the user, the added benefit is it will be even faster to return to numpy.

Fields

data: Vec<T>

rows: usize

cols: usize

Implementations

impl<T> RowMajorMatrix<T>

pub fn new(data: Vec<T>, rows: usize, cols: usize) -> Self

pub fn get(&self, i: usize, j: usize) -> &T

Get a single reference to an item in the matrix.

• i - The ith row of the data to get.
• j - the jth column of the data to get.

pub fn append_row(&mut self, items: Vec<T>)

Add a rows to the matrix, this can be multiple rows, if they are in sequential order in the items.
