23. CAS Problem (3 points): Use a CAS for the following. Turn in a printout of the commands and answers. Find the average size for each of the three pivots from 50 random LU factorizations. MatLab users can use the [L,U]=lu(rand(3)) command. The pivots' averages should be in descending order since a computer always chooses the largest possible entry for a pivot. Also note that "average size means you need to find the absolute values of the pivots before averaging. 23. CAS Problem (3 points): Use a CAS for the following.
