Hi, For real argument, we could easily interface std::riemann_zeta : https://en.cppreference.com/w/cpp/numeric/special_functions/riemann_zeta If you have a compiler (under windows you can install the minGW atoms module), you can run the following script: code=[ "#define

Finally got to the end of the problem and replicated the plot of the Riemann Zeta function on the critical line (s=0.5 + %i*t) Looks pretty close to that shown on the Wikipedia page for the Riemann Zeta Function! function zs1=zeta_0_1(s, n) // Vectorised versionzs1=0k=linspace(1,n,n);

Hi all, After a lot of trial and error, I have managed to get a set of functions to compute the approximations of Riemann's Zeta for negative and positive real values; values of n > 1e6 seem to give better results: function zs=zeta_s(z, n) // Summation loop zs=1; if z == 0 zs
