Module hpo::matrix

A custom matrix for quick row and column-based data access

Matrix is only used within the SimilarityCombiner trait and should not be used for other purposes, as it does not contain many safety guarantees.

Imagine the following matrix / Dataframe

Index	0	1	2	3
0	11	12	13	14
1	21	22	23	24
2	31	32	33	34

use hpo::matrix::Matrix;
let data = vec![11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34];
let m = Matrix::new(3, 4, &data);

for row in m.rows() {
    let v: Vec<String> = row.map(|v| format!("{}", v)).collect();
    println!("[{}]", v.join(", "));
}

// >> [11, 12, 13, 14]
// >> [21, 22, 23, 24]
// >> [31, 32, 33, 34]


for col in m.cols() {
    let v: Vec<String> = col.map(|v| format!("{}", v)).collect();
    println!("[{}]", v.join(", "));
}

// >> [11, 21, 31]
// >> [12, 22, 32]
// >> [13, 23, 33]
// >> [14, 24, 34]

There are no logic checks to ensure that the rows and column match the data length, so callers must ensure this

  A custom matrix for quick row and column-based data access
• Row
  An iterator of the values of a single row of a Matrix
• RowIterator
  Iterates the rows of a Matrix, returning an Iterator over individual row values
