Creates a [f64; 4] array storing data in column major order. If you require data in row major order transpose the matrix first.

pub const fn from_cols_array_2d(m: &[[f64; 2]; 2]) -> DMat2

Creates a 2x2 matrix from a [[f64; 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 const fn to_cols_array_2d(&self) -> [[f64; 2]; 2]

Creates a [[f64; 2]; 2] 2D array storing data in column major order. If you require data in row major order transpose the matrix first.

Panics

Panics if index is greater than 1.

pub fn row(&self, index: usize) -> DVec2

Returns the matrix row for the given index.

Panics

Panics if index is greater than 1.

pub fn is_finite(&self) -> bool

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

Returns true if any elements are NaN.

pub fn transpose(&self) -> DMat2

Returns the transpose of self.

pub fn determinant(&self) -> f64

Returns the determinant of self.

Subtracts two 2x2 matrices.

pub fn mul_scalar(&self, rhs: f64) -> DMat2

Multiplies a 2x2 matrix by a scalar.

pub fn abs_diff_eq(&self, rhs: DMat2, max_abs_diff: f64) -> bool

Returns true if the absolute difference of all elements between self and rhs 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.
