How to I solve following meijerG function

Answer 1

[Walter Roberson]

syms a b epsilon
meijerG((1-b)/2, [], [a/2, -a/2], [], epsilon)

ans = 

char(ans)

ans = '(gamma(-a)*gamma(a/2 + b/2 + 1/2)*exp(epsilon/2)*whittakerM(-b/2, a/2, epsilon))/epsilon^(1/2) + (gamma(b/2 - a/2 + 1/2)*exp(epsilon/2)*gamma(a)*whittakerM(-b/2, -a/2, epsilon))/epsilon^(1/2)'
