Struct LabeledMatrix 

pub struct LabeledMatrix {
    pub values: DMatrix<f64>,
    pub tickers: Vec<String>,
}

A square N×N matrix paired with N ticker labels (used for both row and column indexing — the same labelling pandas applies to a covariance/correlation DataFrame).

Fields

values: DMatrix<f64>

tickers: Vec<String>

Implementations

impl LabeledMatrix

pub fn new(values: DMatrix<f64>, tickers: Vec<String>) -> Result<Self>

pub fn get(&self, row_ticker: &str, col_ticker: &str) -> Option<f64>

Look up [row_ticker, col_ticker].
