Implementations
impl Mat2
[src]
pub const fn zero() -> Mat2
[src]
Creates a 2x2 matrix with all elements set to 0.0
.
pub const fn identity() -> Mat2
[src]
Creates a 2x2 identity matrix.
pub fn from_cols(x_axis: Vec2, y_axis: Vec2) -> Mat2
[src]
Creates a 2x2 matrix from two column vectors.
pub fn from_cols_array(m: &[f32; 4]) -> Mat2
[src]
Creates a 2x2 matrix from a [f32; 4]
stored in column major order. If
your data is stored in row major you will need to transpose
the
returned matrix.
pub fn to_cols_array(&self) -> [f32; 4]
[src]
Creates a [f32; 4]
storing data in column major order.
If you require data in row major order transpose
the matrix first.
pub fn from_cols_array_2d(m: &[[f32; 2]; 2]) -> Mat2
[src]
Creates a 2x2 matrix from a [[f32; 2]; 2]
stored in column major
order. If your data is in row major order you will need to transpose
the returned matrix.
pub fn to_cols_array_2d(&self) -> [[f32; 2]; 2]
[src]
Creates a [[f32; 2]; 2]
storing data in column major order.
If you require data in row major order transpose
the matrix first.
pub fn from_scale_angle(scale: Vec2, angle: f32) -> Mat2
[src]
Creates a 2x2 matrix containing the given scale
and rotation of
angle
(in radians).
pub fn from_angle(angle: f32) -> Mat2
[src]
Creates a 2x2 matrix containing a rotation of angle
(in radians).
pub fn from_scale(scale: Vec2) -> Mat2
[src]
Creates a 2x2 matrix containing the given non-uniform scale
.
pub fn is_finite(&self) -> bool
[src]
Returns true
if, and only if, all elements are finite.
If any element is either NaN
, positive or negative infinity, this will return false
.
pub fn is_nan(&self) -> bool
[src]
Returns true
if any elements are NaN
.
pub fn transpose(&self) -> Mat2
[src]
Returns the transpose of self
.
pub fn determinant(&self) -> f32
[src]
Returns the determinant of self
.
pub fn inverse(&self) -> Mat2
[src]
Returns the inverse of self
.
If the matrix is not invertible the returned matrix will be invalid.
pub fn mul_vec2(&self, other: Vec2) -> Vec2
[src]
Transforms a Vec2
.
pub fn mul_mat2(&self, other: &Mat2) -> Mat2
[src]
Multiplies two 2x2 matrices.
pub fn add_mat2(&self, other: &Mat2) -> Mat2
[src]
Adds two 2x2 matrices.
pub fn sub_mat2(&self, other: &Mat2) -> Mat2
[src]
Subtracts two 2x2 matrices.
pub fn mul_scalar(&self, other: f32) -> Mat2
[src]
Multiplies a 2x2 matrix by a scalar.
pub fn abs_diff_eq(&self, other: Mat2, max_abs_diff: f32) -> bool
[src]
Returns true if the absolute difference of all elements between self
and other
is less than or equal to max_abs_diff
.
This can be used to compare if two Mat2
's contain similar elements. It
works best when comparing with a known value. The max_abs_diff
that
should be used used depends on the values being compared against.
