Signature

parametricSolve: (RXY, Vector FX) $\to$ (Vector FX, DenseMatrix F)

$\begin{params} {\em L} & RXY & A linear ordinary differential or recurrence operator\\ $g_i$\ & FX & polynomials\\\end{params}$

$\begin{retval} Returns $h_1,\dots,h_s$\ and a matrix $A$\ such that for every $... ...y solution of $L y = \sum_{j=1}^m c_j g_j$\ must be of that form.\end{retval}$
