2. Write and call a Matlab function to solve a system of equations with Gauss Elimination with partial pivoting. Be sure that your code can accommodate 10 equations if necessary. Test the program using the following system. Print the values of X1, X2 and X3. (soln: x1 = x2 = x3 = 1) X1 + 212 x3 = 2 5x + 2x2 + 2x3 = 9 - 3x + 5x2 x3 = 1 3. Three masses are suspended vertically by a series of identical springs where mass 1 is at the top and mass 3 is at the bottom. If g = 9.81 m/s2, m1 = 2 kg, m2 = -3 kg, m3 = 2.5 kg, and the k's = 10 kg/s2, solve for the displacements x. Use the Matlab code that you developed in #2
