> 论文的F矩阵是x-error_{k+1}对x-error_{k}的导数结果。代码里面的df_dx是f函数对x-error_{k}的导数，可以计算出F矩阵的一部分。其中f的定义为x_{k+1}=x_{k}+f(x_{k}). 论文中F的表达式可以在esekfom.hpp的predict函数中找到，表达式为多个部分的加和。 > […](#) > ________________________________ 寄件者: wanghe ***@***.***> 寄件日期: 2024年10月28日 下午 03:44 收件者: hku-mars/Point-LIO ***@***.***> 副本: Subscribed ***@***.***> 主旨: [hku-mars/Point-LIO] 关于F矩阵和P矩阵 (Issue #105) This is an external email....
