Struct ArenaMatrix 

pub struct ArenaMatrix {
    pub rows: usize,
    pub cols: usize,
    /* private fields */
}

2D matrix stored contiguously within an arena.

Fields

rows: usize

Number of rows.

cols: usize

Number of columns.

Implementations

impl ArenaMatrix

pub fn new(arena: &Arena, rows: usize, cols: usize) -> Option<ArenaMatrix>

Allocates a rows × cols matrix in arena.

pub fn get(&self, arena: &Arena, r: usize, c: usize) -> Option<f64>

Returns the element at (r, c), or None if out of bounds.

pub fn set(&self, arena: &Arena, r: usize, c: usize, value: f64)

Sets value at (r, c).

pub fn to_vec(&self, arena: &Arena) -> Vec<Vec<f64>>

Converts the matrix to Vec<Vec<f64>> (rows × columns).
