matrix

fn matrix<D>(D rows) -> Matrix<D>

Wraps nested fixed-length rows as a Matrix.

rows is nested numeric data such as [[int; 2]; 2] (or a tuple of equal-length rows). There is no runtime cost: the Matrix is the same data with a type that gives operators matrix meaning (see Matrix).

Parameters#

Returns#

Matrix<D>

Examples#

use tests::assert;
let a = matrix([[1, 2], [3, 4]]);
let sq = a * a;
assert!(sq[0][0] == 7);
assert!(sq[1][1] == 22);
