inquiries about some matrices in the firmware

[AHMAD SHARIFA]

Hello guys ,

I am trying to understand the Crazyflie firmware,can any body answer me what the following matrices represent in the firmware in kalman filter estimator.c

A[STATE_X][STATE_X], S[STATE_PX] , P[STATE_X][STATE_X], h[STATE_DIM]

please help me, I need definition of each one.
It seems to me like

dx=Ax+Bu
Y=cx+Du

is this assumption is correct ?

Hi,
Have you had a look at the papers linked in the kalman filter? As far as I understand, this filter is an implementation from the referenced paper.
