"1.#QNAN" in static optimization
Posted: Wed Nov 16, 2011 12:41 am
Hi all,
I'm doing static optimization for gait trials,
but rarely, static optimization gives 1.#QNAN in a frame.
(e.g. in the messages window,
time = 2.74 Performance =0.379839 Constraint violation = 2.15358e-012
time = 2.75 Performance =0.370833 Constraint violation = 4.20757e-012
time = 2.76 Performance =0.0380169 Constraint violation = 1.#QNAN
time = 2.77 Performance =0.373046 Constraint violation = 1.0988e-012
time = 2.78 Performance =0.389789 Constraint violation = 6.96274e-012)
What is the meaning of 1.#QNAN at time = 2.76?
And is it OK if I fix this frame by averaging the result of time = 2.75 and 2.77?
(It seems that results of all other frames are OK)
Thanks,
