The digamma function, denoted as \\( \\psi(x) \\), is the logarithmic derivative of the gamma function \\( \\Gamma(x) \\). Mathematically, it is defined as: \\\[ \\psi(x) = \\frac\{d\}\{dx\} \\ln(\\Gamma(x)) = \\frac\{\\Gamma'(x)\}\{\\Gamma(x)\} \\\] where \\( \\Gamma'(x) \\) is the derivative of the gamma function.
