macro_rules! tensor {
    (@count) => { ... };
    (@count $head:tt $($tail:tt)*) => { ... };
    ($elem:expr; $n:expr) => { ... };
    ($($x:expr),*) => { ... };

Macro for creating vectors and matrices.

To use this macro, import Numeric as follows:

#[macro_use(tensor)]
extern crate numeric;

Examples

1D tensor (vector):

let x = tensor![1.0, 2.0, 3.0];

2D tensor (matrix):

let x = tensor![1, 0; 3, 2; 5, 4];

1D tensor filled with a single value:

let x = tensor![2.0; 5];
