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. WebMay 6, 2024 · To illustrate the savings you can get by storing an appropriate matrix as a sparse matrix, let's take a pretty favorable example for sparse: a matrix with only a few non-zero elements, the identity.
