A small extra that introduces quite a big problem for me: the
gsl_fs_ellint_Kcomp function takes the sqrt of the argument of Wolfram's
EllipticK, meaning that while Wolfram's EllipticK can perfectly handle
things like
EllipticK(-.4)
>
I see no (easy) way of doing such a thing in terms of GSL's elliptic
functions.
There may be a workaround for this, but I'm not too well versed in these
things, the function popped up in an analytical solution to an integral I
have to calculate.
Thanks!
