function P = sym(P)

% SYM -- built-in SYM, extended to matrix polynomials
%
%        P = sym(P)
%
% Convert P.coef to type 'sym' (symbolic variable). This is
% only useful P is numerical, and its entries are simple enough so that 
% Matlab will recognize what they are (integers, simple integer roots,
% simple multiples of pi, etc.)
