WebPython PyMap3d has more conversions. PyMap3d can be accessed from Matlab by commands like: lla = py. pymap3d. geodetic2ecef ( x, y, z) In particular, since PyMap3D uses Astropy for ECI transformations the accuracy will generally be better for eci2* or *2eci functions. All other functions should have equivalent accuracy with Matlab vs. Python. According to this other Stack Overflow question it seems that I need to convert to Earth Centered Earth Fixed (ECEF) coordinates as an intermediate step (so ECI --> ECEF --> Lat/Lon/Alt). I know ECI and ECEF share the same origin point (the center of mass of Earth) and the same z-axis that points to the North Pole.
