Unfortunately the implementation in Mathematica is for numerical matrices only as the help text states:
SchurDecomposition[m] yields the Schur decomposition for a numerical matrix m,...

I know I can run the matrix through the numerical N[] command before I pass it to SchurDecomposition[], but I'd like to be able to get the exact unitary and upper triangular matrices which decompose a given matrix. Any thoughts on a work around, or is this futile? >
