Macro artha::matrix

macro_rules! matrix {
    ( $( $x:expr ),* ) => { ... };
}

Creates a matrix containing the arguments.

matrix! allows Matrix to be define in similary manner to Vec or arrays. Since Matrix is a 2D matrix, you have to put [] around the inner data as well.

For example:

let x1 = matrix![[2., 3.],[1., 2.],[3., 5.]];
let x2 = matrix![[2, 3, 5],[1, 2, 5]];
let x3 = matrix![[3],[4],[5]];
