Recently solvers for triangular systems that can work for general types has been added, but there is no general solver that works for rational matrices.
As Stefan pointed out, overflow is likely to be a problem. I have just tried a lu rational factorisation and it overflows most of the time for 5x5 matrices of Int64, but of course you can use BigInts. There is some functionality for this in Sage (sagemath.org). 2014/1/8 David Zhang <[email protected]> > Does Julia have any packages that perform linear algebra on > rational-valued matrices?
