% Converts attitude increments to rate.
To prevent transients set aOld = DupVect(a,m) upon initialization. You can
initialize by passing AI2Rate only 2 or 3 arguments.
--------------------------------------------------------------------------
Form:
[w, aOld] = AI2Rate( a, dT, m, aOld )
--------------------------------------------------------------------------
------
Inputs
------
a (n,:) Attitude increments
dT (1,1) Time between increments
m (1,1) Order (0, 1 or 2)
aOld (n,m) Last m attitude increments
-------
Outputs
-------
w (n,:) Estimated rate
aOld (n,m) Last m attitude increments
