Roots of a matrix of polynomial coefficients

Hello,

I know how the roots function work in MATLAB. It takes a "vector" C containing coefficients of "a" polynomial, and then it'll spit out the roots of that polynomial. But now I have a Matrix that contains the coefficients of different polynomials and I'd like to find their roots? How Do I do that? Is there anyway to do that using the roots function?

Thank you!

Use a loop, or equivalent such as arrayfun.

There might also be a way using the symbolic toolbox and solve() and double(), maybe http://www.mathworks.com/help/symbolic/poly2sym.html . But that would certainly not be efficient.
