Macro numb_rs::mat

macro_rules! mat {
    () => { ... };
    ($($($item : expr), +) ; +) => { ... };
    ($val : expr => $m : expr, $n : expr) => { ... };
}

With a focus on being concise: This macro will create a matrix using syntax similar to matlab A semicolon ‘;’ represends a new matrix row

example 1:

let a = mat![
    0, 1, 2;
    3, 4, 5
];

will provide a 3x2 matrix as specified

example 2:

It’s also possible to initialise a matrix with a given value This uses a different syntax to standard rust code due to a semicolon being used to denote a row change. for instance:

let x = [0.;5];

is translated to:

let x = mat![0. => 5, 1];

where 5, 1 represent m and n, i.e. the row and column lengths respectively
