Method get

src/matrix.rs:554–560

Returns the element of the matrix at row `row` (indexing starts at zero) and column `col` or `None` if row or column does not exist. ``` # #[macro_use] extern crate rustml; use rustml::*; # fn main() { let m = mat![ 1.0, 1.5; 2.0, 2.5; 5.0, 5.5 ]; assert_eq!(m.get(0, 1).unwrap(), &1.5); assert_eq!(m.get(2, 0).unwrap(), &5.0); assert!(m.get(3, 0).is_none()); # } ```
