The sym2poly(P) function returns a vector containing the coefficients of the polynomial P.

The indeterminate of P is determined by findsym(P,1).

$\mathrm{sym2poly}\left(y^5+2y^4+3y^3+4y^2+5y+6\right)$

$\left[\begin{array}{c}1\\ 2\\ 3\\ 4\\ 5\\ 6\end{array}\right]$

$\mathrm{sym2poly}\left(y^5+2y^4+3y^3+4y^2+5y+6x\right)$

$\left[\begin{array}{c}6\\ y^5+2y^4+3y^3+4y^2+5y\end{array}\right]$
