Generalization using Software (Problems to complete) Imagine trying to solve a 1,800,000 by 900,000 system of linear equations. This was the problem facing NAD (North American Datum) geologists to establish accurate GPS points on the Earth's surface. The system is obviously over determined and thus has no solution in the ordinary sense, but it does have a least square solution (where the normal equations are a 928,735 by 928,735 system of linear equations!) [3] To get an idea of how to solve these type of large problems (and to use software to assist in the solution process), answer the following questions: 1. [5 points] Verify the example given above by working out the matrix operations (multiplications, etc.)
