         <h2>The FACTORIZE object to the rescue<a name="12"></a></h2>
         <p>The FACTORIZE method is just as easy to use as INV, but just as fast and accurate as BACKSLASH, LU, QR, CHOL, and LINSOLVE.</p>
         <p>F = factorize(A) computes the factorization of A and returns it as an object that you can reuse to solve a linear system with
            x=F\b.  It picks LU, QR, or Cholesky for you, just like BACKSLASH.

         <p>S = inverse(A)
