determinant



Hello to all!

Is it true, that "determinant(M) computes the determinant of M by a 
method similar to Gaussian elimination" ?

I've try:
-------------------------------
A:genmatrix(lambda([i,j],random(20)),15,15)$

triangularize(A)$
-------------------------------
- evaluation took 0.0800 seconds (0.0800 elapsed)

-------------------------------
determinant(A);
-------------------------------
- evaluation took 11.3000 seconds (11.3000 elapsed)

This is very strange, isn't it?
