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.
WebThis suggests an inductive method of defining the determinant of any square matrix in terms of determinants ... Now expand this along the top row to get , the product of the main diagonal entries.
