Trac #18040: Minimal polynomials of matrices over SymbolicRing
In Sage 6.6.rc0: {{{ sage: M = matrix.identity(SR, 2) sage: type(M) <type 'sage.matrix.matrix_symbolic_dense.Matrix_symbolic_dense'> sage: M.minpoly() Traceback (most recent call last): ... NotImplementedError: is_squarefree() is only implemented for polynomials over principal ideal domains }}} Trying to work around #11126 fails with a different error: {{{ sage: SR in Fields() True sage: M.minpoly() Traceback (most recent call last): ... NotImplementedError: }}} This ticket implements `minpoly()` for matrices over `SymbolicRing` using the function `minimalPoly()` from Maxima's `diag` package.
