四元数的隆戈库塔法，利用隆戈库塔队四元数进行更新，可以从中提取出载体姿态信息(Quaternion Longo Kutta method, using Longo Coulthard team quaternion update, can be extracted from vector-profile information)

这次上传的绝对是好东西，数值优化，关键是对不同函数进行运算。这次将无约束测试问题上传，可作为论文数值计算使用。注：本人本科毕业论文做的是无约束优化，研究生做的是结构方程(LISREL)、数值优化、蚁群算法，可以进行交流，联系QQ272958823(Test function for optimation!)

This file compares three different versions of the Kalman filter. The Kalman filter is used for recursive parameter estimation. The Kalman filter can handle noisy measurements. The first implemented filter (fcn_KF) is the Kalman filter with standard update of the covariance matrix P. The covariance matrix reflects the uncertainties of the predictions. To improve the numerical stability Potter developed a square root update (fcn_KF_SRP) of the covariance matrix P. Another version is the square root covariance update via triangularization (fcn_KF_SRT). This file generates a model. Then the three Kalman filters perform an estimation of the model parameter. At the end the results are compared. Sources: Simon, D. (2006): Optimal state estimation Kaminski, P. (1971): Discrete Square Root Filtering: A Survey of Current Techniques Golub, G.
