Implementations
impl DMat2
[src]
impl DMat2
[src]pub const IDENTITY: Self
[src]
pub const IDENTITY: Self
[src]A 2x2 identity matrix, where all diagonal elements are 1
, and all off-diagonal elements are 0
.
pub fn from_cols(x_axis: DVec2, y_axis: DVec2) -> Self
[src]
pub fn from_cols(x_axis: DVec2, y_axis: DVec2) -> Self
[src]Creates a 2x2 matrix from two column vectors.
pub fn from_cols_array(m: &[f64; 4]) -> Self
[src]
pub fn from_cols_array(m: &[f64; 4]) -> Self
[src]Creates a 2x2 matrix from a [S; 4]
array 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) -> [f64; 4]
[src]
pub fn to_cols_array(&self) -> [f64; 4]
[src]Creates a [S; 4]
array 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: &[[f64; 2]; 2]) -> Self
[src]
pub fn from_cols_array_2d(m: &[[f64; 2]; 2]) -> Self
[src]Creates a 2x2 matrix from a [[S; 2]; 2]
2D array 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) -> [[f64; 2]; 2]
[src]
pub fn to_cols_array_2d(&self) -> [[f64; 2]; 2]
[src]Creates a [[S; 2]; 2]
2D array storing data in column major order.
If you require data in row major order transpose
the matrix first.
pub fn from_diagonal(diagonal: DVec2) -> Self
[src]
pub fn from_diagonal(diagonal: DVec2) -> Self
[src]Creates a 2x2 matrix with its diagonal set to diagonal
and all other entries set to 0.
pub fn from_scale_angle(scale: DVec2, angle: f64) -> Self
[src]
pub fn from_scale_angle(scale: DVec2, angle: f64) -> Self
[src]Creates a 2x2 matrix containing the combining non-uniform scale
and rotation of
angle
(in radians).
pub fn from_angle(angle: f64) -> Self
[src]
pub fn from_angle(angle: f64) -> Self
[src]Creates a 2x2 matrix containing a rotation of angle
(in radians).
pub fn from_cols_slice(slice: &[f64]) -> Self
[src]
pub fn from_cols_slice(slice: &[f64]) -> Self
[src]Creates a 2x2 matrix from the first 4 values in slice
.
Panics
Panics if slice
is less than 4 elements long.
pub fn write_cols_to_slice(self, slice: &mut [f64])
[src]
pub fn write_cols_to_slice(self, slice: &mut [f64])
[src]Writes the columns of self
to the first 4 elements in slice
.
Panics
Panics if slice
is less than 4 elements long.
pub fn is_finite(&self) -> bool
[src]
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 determinant(&self) -> f64
[src]
pub fn determinant(&self) -> f64
[src]Returns the determinant of self
.
pub fn inverse(&self) -> Self
[src]
pub fn inverse(&self) -> Self
[src]Returns the inverse of self
.
If the matrix is not invertible the returned matrix will be invalid.
pub fn mul_scalar(&self, other: f64) -> Self
[src]
pub fn mul_scalar(&self, other: f64) -> Self
[src]Multiplies a 2x2 matrix by a scalar.
pub fn abs_diff_eq(&self, other: &Self, max_abs_diff: f64) -> bool
[src]
pub fn abs_diff_eq(&self, other: &Self, max_abs_diff: f64) -> 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 matrices 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.
For more see comparing floating point numbers.
