Lag-New-and-spl
- 包含拉格朗日、牛顿插值及三次样条的数值积分函数及算法-Numerical integration function and algorithm for the Lagrange, Newton interpolation and the three spline
lbfgs
- L-BFGS算法比较适合在大规模的数值计算中,具备牛顿法收敛速度快的特点,但不需要牛顿法那样存储Hesse矩阵,因此节省了大量的空间以及计算资源。-Limited-memory BFGS (L-BFGS or LM-BFGS) is an optimization algorithm in the family of quasi-Newton methods that approximates the Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorit
