1. Let A be the n x n Hilbert matrix with entries 1 %3D i+j Hilbert matrices are symmetric Hankel matrices which are theoretically positive definite, but very ill-conditioned. (a) Let y(n) = log,, K(A). Compute y(n) for n = 3:12 and determine a simple linear formula which will approximate y(n) for any n in that range. (b) Using the rank command, find the smallest n for which A is numerically singular.k
