Hello, welcome to the elliptic project chat room. Type here your questions!

Hi Igor, I came across your Elliptic MATLAB / Octave project when trying to find implementations of the Weierstrass P function, and noticed that it is a work in progress
Correct me if I'm wrong, but can this not simply be implemented in the following way:
function P = WeiP(z,e1,e2,e3)
m = (e2 - e3)/(e1 - e3);
w = z*sqrt(e1 - e3);
sn = ellipj(w,m);
P = e3 + (e1 - e3)/(sn^2);
end
When comparing the output with other languages (R, Mathematica) it appears to work fine

@haessar Ooo, thank you for this idea! This is a nice representation of Weierstrass P function with Jacobi functions, I think we will do it so.

Just to make one correction to my code, (sn^2) should be changed to (sn.^2) to account for when z is a vector.

Sure thanks! I'll merge it in a near future.
