Struct Matrix 

pub struct Matrix {
    pub n_rows: usize,
    pub n_cols: usize,
    pub row_names: Vec<String>,
    pub col_names: Vec<String>,
    pub data: Vec<f64>,
}

Row-major dense matrix with optional row/column labels.

Fields

n_rows: usize

n_cols: usize

row_names: Vec<String>

col_names: Vec<String>

data: Vec<f64>

Implementations

impl Matrix

pub fn row(&self, i: usize) -> &[f64]

pub fn column(&self, j: usize) -> Vec<f64>

Materialise column j into a fresh Vec (row-major storage strides).

pub fn read(path: Option<&Path>) -> Result<Matrix>

Read from a file (- or None = stdin).

Errors

Missing file, empty input, ragged body, non-numeric cell.

pub fn parse(text: &str) -> Result<Matrix>

Parse tab-separated matrix. Header detected by leading tab (empty top-left).

Errors

Empty input, ragged body, non-numeric cell.
