Correcting latitude calculation

copilot:all

🛠️ PR Summary

_{Made with ❤️ by Ultralytics Actions}

Updated MATLAB path instructions and improved latitude calculation function.

Formatted the command lines in the installation section of the README for better readability.
Corrected the latitude calculation formula in the ecef2lla.m function by changing ep and es to ep^2 and es^2 respectively.

Readability Improvement: The indented code blocks in the README ensure clarity when copying commands, facilitating easier setup. 🛠️
Accuracy Enhancement: The fix in the Earth-centered Earth-fixed (ECEF) to latitude, longitude, and altitude (LLA) conversion function leads to more accurate geographic coordinate calculations. 🌐 This is crucial for tasks in navigation, geodesy, and aerospace engineering where precise location data is necessary. 🚀
