The function golub in the NCM directory is named after Stanford professor Gene Golub. The function generates test matrices with random integer entries. The matrices are very badly conditioned, but Gaussian elimination without pivoting fails to produce the small pivots that would reveal the large condition number.

(a) How does condest(golub(n)) grow with increasing order n? Because these are random matrices you can’t be very precise here, but you can give some qualitative description.

(b) What atypical behavior do you observe with the diagonal pivoting option in lugui(golub(n))?

(c) What is det(golub(n))? Why?
