Read the help on the function inv(). Copy paste the lines from the help page to the comman window. Later in the module we will discuss solving linear systems of equations Ax = b You should know now that there are two ways to do this in Matlab: x = inv(A) * b and x = A\b. Try both for the matrix A and vector b from the previous two questions. You can tes™ that the solution is correct by computing norm(A * x - b). This is called the residual Compute the residual for each of your solutions.
