Struct dzahui::solvers::fem::basis::two_variables::polynomials_2d::Transformation2D

pub struct Transformation2D {
    a: f64,
    b: f64,
    c: f64,
    d: f64,
}

General Information

Represents a matrix transformation in 2D. A normal matrix composed of vectors or arrays is not used since more control over the traits that are implemented on the struct makes latter implementations easier.

Fields

• a - Element [0,0] in matrix
• b - Element [0,1] in matrix
• c - Element [1,0] in matrix
• d - Element [1,1] in matrix

Fields

a: f64

b: f64

c: f64

d: f64

Implementations

pub fn new(a: f64, b: f64, c: f64, d: f64) -> Transformation2D

New instance

pub fn inverse(self) -> Transformation2D

Inverse of a 2x2 matrix
