ECEF to ECI velocity conversion
In the tests functions for ECEF/ECI validation values are taken from matlab examples. The functions use position data, but not velocity data.
I found that the resulting velocity was different from that in the matlab documentation after conversion from ECEF to ECI.
I convert (3832 -4024 4837) from ECEF to ECI at datetime (2019, 1, 4, 12)
I expect: (-3384 -4887 4843)
I get: (-3004. -4669. 4842)

Python : 3.9.0
Pymap3d : 2.9.1

the pymap3d doesn't convert velocities for ECEF2ECI
