Z Function Algorithm

Siegel Z-function, the Riemann – Siegel zeta-function, the Hardy function, the Hardy Z-function and the Hardy zeta-function. It follows from the fact that the Riemann-Siegel theta-function and the Riemann zeta-function are both holomorphic in the critical strip, where the imaginary part of t is between −1/2 and 1/2, that the Z-function is holomorphic in the critical strip also.
