Struct B2Mat22 

pub struct B2Mat22 {
    pub ex: B2vec2,
    pub ey: B2vec2,
}

A 2-by-2 matrix. Stored in column-major order.

Fields

ex: B2vec2

ey: B2vec2

Implementations

impl B2Mat22

pub fn new(c1: B2vec2, c2: B2vec2) -> B2Mat22

Construct this matrix using columns.

pub fn new_scalars(a11: f32, a12: f32, a21: f32, a22: f32) -> B2Mat22

Construct this matrix using scalars.

pub fn set(&mut self, c1: B2vec2, c2: B2vec2)

initialize this matrix using columns.

pub fn set_identity(&mut self)

Set this to the identity matrix.

pub fn set_zero(&mut self)

Set this matrix to all zeros.

pub fn zero() -> Self

pub fn get_inverse(&mut self) -> B2Mat22

pub fn solve(self, b: B2vec2) -> B2vec2

solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.
