中文版:超球多项式在线计算器

Gegenbauer Polynomial Calculator
N(超球多项式阶数,0 ≤ N ≤ 10)
λ(超球参数,0.5 到 6、步长 0.5)
计算结果
C₄⁽2⁾(x)80x⁴ − 48x² + 3
首项系数2⁴·(λ)₄/4! = 80
正交权[−1, 1] 上权 (1−x²)^(λ−1/2)

递推

(n+1)·Cₙ₊₁⁽ᵌ⁾ = 2(n+λ)·x·Cₙ⁽ᵌ⁾ − (n+2λ−1)·Cₙ₋₁⁽ᵌ⁾

C₃⁽¹⁾(x) = 8x³ − 4x(恰为 U₃);C₄⁽²⁾(x) = 80x⁴ − 48x² + 3

Gegenbauer(超球)多项式统一了 [−1, 1] 上的各向同性正交族:λ=1/2 退化为切比雪夫第二类、λ=1 为勒让德、λ→0 极限是第一类。高维球面上的球谐展开、超球调和与多元切比雪夫逼近都由它承担。
