%% Special Values
% For certain parameter values, symbolic evaluation of the Hurwitz zeta function returns special values that are related to other symbolic functions.
% For a = 1, the Hurwitz zeta function returns the Riemann zeta function zeta(s).

syms s a;
Z = hurwitzZeta(s,1)

% For s = 2, the Hurwitz zeta function returns the first derivative of the digamma function psi(1,a).

Z = hurwitzZeta(2,a)

% For nonpositive integers s, the Hurwitz zeta function returns polynomials in terms of a.

Z = hurwitzZeta(0,a)
Z = hurwitzZeta(-1,a)
Z = hurwitzZeta(-2,a)
