Mittag-Leffler 函数 E_α(z) = Σ z^k / Γ(αk+1) 是指数函数的「分数阶推广」：α=1 时逐项恢复 e^z，α=2 时给出 cosh√z，α=1/2 时与误差函数联姻。分数阶微积分里 (d/dt)^α 的响应函数正是 E_α(−λt^α)——从反常扩散（亚扩散的慢幂律尾巴）到黏弹性材料的蠕变柔量、分数阶控制器的阶跃响应，它都是解的骨架。
数值实现用递推 term_k = term_(k−1)·z·Γ(α(k−1)+1)/Γ(αk+1) 配合 Kahan 补偿求和，避免 pow(z,k) 与 exp(lnΓ) 的双重大数溢出；α=1/2、z ≤ 0 的闭式 e^(z²)·erfc(−z) 用 300 层连分式 erfc 做独立对拍。
