function poly = polynom(coeffs)
% POLYNOM  Create a polynomial :mat:func:`Func` instance.
% poly = polynom(coeffs)
% The polynomial coefficients are specified by a vector
% ``[a0 a1 .... aN]``. Examples:
%
% .. code-block:: matlab
%
%     polynom([-2 6 3])          %3x^2 + 6.0x - 2
%     polynom([1.0 -2.5 0 0 2])  %2x^4 - 2.5x + 1
%
% :param coeffs:
%     Vector of polynomial coefficients
% :return:
%     Instance of class :mat:func:`Func`
