ecef2ned vs. ecef2nedv

What is the difference between ecef2ned ( http://www.mathworks.com/help/map/ref/ecef2ned.html ) and ecef2nedv ( http://www.mathworks.com/help/map/ref/ecef2nedv.html )?

Hi David,

I understand you want to know the difference between the functions 'ecef2ned' and 'eced2nedv' functions in MATLAB

1. 'ecef2ned' converts Earth-Centered, Earth-Fixed (ECEF) coordinates to North-East-Down (NED) coordinates.

• It takes ECEF coordinates as input and provides NED position coordinates as output.
• 'ecef2ned` does not incorporate vector transformation.

2. 'ecef2nedv' is an extension of `ecef2ned` that includes vector transformation in addition to position transformation.

• It takes ECEF coordinates and a corresponding vector as input.
• `ecef2nedv` converts ECEF coordinates to NED coordinates and transforms the vector from the ECEF frame to the NED frame.
• The output of `ecef2nedv` includes both the position coordinates (NED) and the transformed vector components relative to a specific reference point.

For better understanding, refer to the following documentation from MathWorks

• ecef2ned - http://www.mathworks.com/help/map/ref/ecef2ned.html
• ecef2nedv - http://www.mathworks.com/help/map/ref/ecef2nedv.html

I hope this resolves the query you had
