Struct euler::Mat2

#[repr(C)]
pub struct Mat2(_);

2x2 column major matrix.

Methods

impl Mat2

fn identity() -> Self

Returns the identity matrix.

fn invert(self) -> Mat2

Computes the inverse of this matrix.

Panics

Panics if the matrix is not invertible.

fn try_invert(self) -> Option<Mat2>

Computes the inverse of this matrix, returning None if non-invertible.

Examples

let m = mat2!();
assert_eq!(m.try_invert(), Some(mat2!()));

let m = mat2!(
    0.0, 0.0,
    0.0, 0.0,
);
assert_eq!(m.try_invert(), None);
