Struct AffineTransform 

pub struct AffineTransform {
    pub a: [f64; 25],
    pub b: [f64; 5],
    pub prob: f64,
}

An affine transformation for IFS: w(x) = A·x + b.

Fields

a: [f64; 25]

5x5 contraction matrix (flattened, row-major)

b: [f64; 5]

Translation vector (5D)

prob: f64

Probability weight

Implementations

impl AffineTransform

pub fn identity() -> Self

Identity transform.

pub fn apply(&self, x: &[f64; 5]) -> [f64; 5]

Apply transform to a 5D coordinate.

pub fn apply_inverse_1d(&self, y: f64, dim: usize) -> f64

Apply the inverse of the 1D diagonal approximation: T^{-1}(y) = (y - b) / a_diag.

For the diagonal element a[i*5+i] (the contraction factor for dimension i). If a_diag ≈ 0, returns 0.0 (degenerate case).
