Question 1 2 -3 2 4 26 -5 3b28 A--2 4 -10 -9 2 64-2 1. Use Gaussian Elimination method to transform the given linear system Ax-b to a triangular linear system. (calculate on paper and give the final triangular linear system) 2. Use Gaussian Elimination method to transform the given linear system Ax-b to a triangular linear system. (write your own Matlab code to implement and give the final triangular linear system) (graduate student only) 3. Use a library routine for Gaussian elimination to transform the given linear system Ax-b to a triangular linear system. (Hint: search the library routine linalg::gaussElim) 4. Implement forward or backward algorithm to get the solution for the triangular linear system. Then give the general format for the algorithm you used. 5. Use Matlab library routines to solve the given linear system Ax-b. (search to find at least two library routines)
