Select the correct statements Select one or more: a. The numerical answer of the solution of a linear system of equations using the PA-LU contains errors b. Using LU decomposition to solve a system of linear equations having exactly one solution can fail c. Cramer's rule is a very efficient method to solve linear systems of equations d. Gauss elimination algorithms with partial pivoting are restricted to small systems (typically less than 4- 5 equations) as their computational effort is large De LU decomposition is significantly more efficient than the naive Gauss elimination algorithm for solving a system Az-b
