The Jacobi

Hi, @thlsealight
Thanks for your nice work!
Is that the derivative of r with respect to R_b_r ?

[thlsealight]

I know what you are thinking, but I think this formula is not correct. Because all the two terms in formula (10) are from $p^{r_i,h}$. I suggest you read the paper and the codes carefully.

感谢回复，我就用中文了。
所以，这里求导，是整个等式$p^{r_i,h}$，对$R^{b,r}$右扰动，展开化简，舍去二次小项吗？.

对的，扰动舍去二次项，就这个雅克比复杂一些。没有问题我就直接关闭这个issue了。
