| Summary: | 0000573: Wrong result for Jacobian elliptic function 'Dn' | ||||
| Description: |
Going for: alglib::jacobianellipticfunctions(u, m, sn, cn, dn, ph); with: u = -13.3077 and m = 0.9162 yields: sn alglib -1 cn alglib 3.06162e-16 dn alglib 0.147015 Sn and Cn are correct, while Dn, which should be sqrt(1-m*sn*sn) is 0.147015 instead of the expected 0.289482 |
