solve3x3
fun solve3x3(a00: Double, a01: Double, a02: Double, a10: Double, a11: Double, a12: Double, a20: Double, a21: Double, a22: Double, b0: Double, b1: Double, b2: Double, singularityEpsilon: Double = 1.0E-10): Triple<Double, Double, Double>?
Solves the 3×3 linear system Ax = b via Cramer's rule. Returns null when |det(A)| is below singularityEpsilon.
