Struct polyhorn_ui::linalg::inter::LaplaceExpansion3D

pub struct LaplaceExpansion3D<'a, T> where
    T: Float,  {
    pub transform: &'a Transform3D<T>,
    pub blue: [T; 6],
    pub red: [T; 6],
}

Container that memoizes the results of laplace expansion that is used to compute the determinant, adjugate and (as a result) the inverse of a 3D transformation matrix.

Fields

transform: &'a Transform3D<T>

Reference to the original transformation matrices that we will need to compute the adjugate matrix.

blue: [T; 6]

Coefficients of the blue areas.

red: [T; 6]

Coefficients of the red areas.

Implementations

impl<'a, T> LaplaceExpansion3D<'a, T> where
    T: Float, 

pub fn new(transform: &Transform3D<T>) -> LaplaceExpansion3D<'_, T>

Returns a new laplace expansion of the given transformation matrix.

pub fn determinant(&self) -> T

Returns the determinant of this transformation matrix.

pub fn adjugate(&self) -> Transform3D<T>

Returns the adjugate of this transformation matrix.

pub fn inverse(&self) -> Option<Transform3D<T>>

Returns the inverse of this transformation matrix (if it exists) using the determinant and adjugate. If the determinant is zero, this function returns None.
