Coordinate Transformation

The code performs a 2D Helmert transformation to convert ED50 projected coordinates to ITRF coordinates. The steps are:

1. Compute the average coordinates of the reference points in both ED50 and ITRF systems.
2. Center the coordinates by subtracting the average.
3. Normalize the ED50 coordinates by dividing by a scale factor D.
4. Construct the design matrix (A) and observation vector (L) for the transformation.
5. Solve for the transformation parameters [tx', ty', a', b'] using Least Squares Estimation.
6. Apply translation, rotation, and scale to convert ED50 coordinates to ITRF coordinates.
7. Compute residuals, standard deviation, and covariance matrix to assess the reliability of the transformation
