Does Julia have any support for linear algebra on rational-valued matrices? Currently, most linear algebra functionality seems to be provided by BLAS/LAPACK, which only support operations on floating-point matrices.
I am interested in this because I would like to use Julia to derive high-order numerical integration methods, whose coefficients are the solutions of rational linear system. (Continuation from http://stackoverflow.com/questions/20985783/rational-matrix-division-in-julia )
