Estimating the Number of Correct Digits

python

Do you know how accurate your solutions are? The ability to print a solution to 16 digits does not imply that we actually have an answer that is accurate to that precision. For this problem, you must solve a linear system and indicate how many accurate digits you have in your solution. You may use functions from numpy. linalg for this problem. numpy. linalg. solve and numpy. Lina lg. cond may be particularly useful. If I run the same code several times, sometimes my solution is correct and sometimes it is not. What is going on? One possibility is that you are rounding incorrectly. Think about this: If I have 4.9 accurate digits, should I say that five of my digits are accurate, or four of my digits are accurate? The setup code gives the following variables: Name Type n x n numpy float64 array n numpy float64 array Description A matrix b vector Your code snippet should define the following variables: Name correct_digits user_code.py 1 Type integer numpy array Description indicates how many meaningful digits there are in x the x that solves Ax = b
