Hi all!
I have a nonlinear system of 11 algebraic equations with 6 unknowns.
The problem which i try to solve and from which this system is coming is the analyzing of some vectors (in 3d space) onto three refrence axes (x,y,z). I know the amplitude of the vectors and the roll, pitch, and yaw...
Finally I found my way. The numerical differentiations I tried were really noisy.
A Butterworth high pass filter that I designed with the help of the FDAtool did the trick finally.
Thanks for helping ;)
Hi, I have position data from a tracker and I want to calculate velocity and acceleration. Simple [x(i)-x(i-1)]/?t and some other formulaes does not give good results.
I want to try to use a highpass filter with slope '1' (20db/dec) from 0 to 10 Hz (my area of interest) to calculate the...
