Coordinate Transformation from ENU (East-North-Up) to ECEF (Earth-Centered Earth-Fixed) System
MATLAB implementation for coordinate conversion from ENU (East-North-Up) frame to ECEF (Earth-Centered Earth-Fixed) system with supporting documentation. The main function ENVtoECEF takes ENU origin latitude/longitude coordinates and ENU point data as input parameters, and outputs corresponding latitude, longitude, and altitude (LLA) coordinates. The implementation includes WGS-84 ellipsoid parameters and transformation algorithms for precise geospatial calculations.
