"WebA = eye (10)*0.0001; The matrix A has very small entries along the main diagonal. However, A is not singular, because it is a multiple of the identity matrix. Calculate the determinant of A. d = det (A) d = 1.0000e-40. The determinant is extremely small. A tolerance test of the form abs (det (A)) < tol is likely to flag this matrix as singular.
