gives the Riemann-Siegel function Z(t).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • , where theta is the Riemann-Siegel theta function, and zeta is the Riemann zeta function.
  • for real t.
  • Z(t) is an analytic function of t except for branch cuts on the imaginary axis running from to ±i ∞.
  • For certain special arguments, RiemannSiegelZ automatically evaluates to exact values.
