Problem 7 (10 points) For a series of matrices A of order is, record the execution time for computing the LU factor ization of A. Using linear least squares, t a cubic polynomial (that is nd its coeicients) to the execution times as a function of as. To obtain reliable results, use a wide range of values for n, say in increments of 100 from 100 up to several hundred (or thousands), depending on your machine. Try also to obtain more accurate timing results by averaging several runs for a given matrix size. 0 Plot the CPU time versus 71 and the cubic polynomial. o The resulting cubic polynomial could be used to predict the execution time for other values, e.g. for very large values of n. What is the predicted execution time for a matrix of order 10,000
