解无约束优化问题的锥模型拟牛顿信赖域算法。不同与传统的二次模型方法。(A quasi-Newton algorithm based on the simple dogleg method is developed.)

可进行最小二乘法线性拟合输出，包含源代码及生成后的程序(Least-squares linear fit can be output)

《Optimal State Estimation - Kalman, H Infinity, and Nonlinear Approaches》 一书的配套源码，包括了Kalman Filter、Hinf Filter、Particle Filter等的Matlab源码(《Optimal State Estimation- Kalman, H Infinity, and Nonlinear Approaches》source code，including Matlab code of Kalman Filter、Hinf Filter、Particle Filter.)

有限元热计算的算例，做有限元热分析的朋友比较有用(Finite element calculation of hot example, to do finite element analysis of hot Friend more useful)

比较JPLDE405的切比雪夫系数导出的位置与低精度月球坐标分析。(Comparative Analysis of JPL DE405 cut Chebyshev coefficients derived position with low accuracy lunar coordinates.)

本程序用于电力系统不对称故障计算，matlab实现，希望有所帮助(This procedure for the asymmetry of power system fault calculation, matlab realize the hope that help)

附件中是我用Fortran写的lorenz混沌吸引子的lyapunov指数谱产生程序。包括三部分内容：如何产生lorenz吸引子，详细注释，如何计算lyapunov指数谱。 需要的话也可以单独提取子程序中的四阶龙格库塔算法。 希望有所用。(Annex is written in Fortran I used the Lorenz chaotic attractor of lyapunov index spectrum generation process. Includes three parts: how to generate Lorenz attractor, detailed notes, how to calculate the spectrum lyapunov index. If necessary, extraction can also be a separate subroutine in the fourth-order Runge-Kutta algorithm. Would like to see used.)
