The numbers are "nice", so both results are exact. I know …
WebThe Crout method was developed by the American mathematician Prescott Crout. In the Crout e- m thod, the upper triangular matrix U has its diagonal elements all set to one [11]. The Crout method likewise requires n2 number of operations. The Cholesky factorization works for symmetric positive definite matrices.
