Hi, i have a few questions regarding some math and estimation stuff.
Lets say i have 2 variables, the x, y coordinates of 2 points.
How am i going to compute the covariance matrix of the 2 points?
What exactly is a jacobian matrix about?
I understand how to derive a jacobian matrix from a given process
equation but i do not really understand the usage/purpose of it.
If i got a nonlinear process, how do i linearise it? Has this got
anything to do with the jacobian matrix above?
