delip(1)

NAME
delip - elliptic integral

CALLING SEQUENCE
[r]=delip(x,ck)

DESCRIPTION
returns the value of the elliptic integral with parameter ck :
r=integral from 0 to x {dt / sqrt((1-t^2)*(1-ck^2*t^2))}
x real and positive. When called with x a real vector r is evaluated at each coordinate of x.
