delip

delip — elliptic integral

Calling sequence

[r]=delip(x,ck)

`x`	: real number (or real vector)
`ck`	: real number between -1 and 1
`r`	: real or complex number (or vector)

returns the value of the elliptic integral with parameter ck :

x real and positive. When called with x a real vector r is evaluated for each entry of x.



ck=0.5;
delip([1,2],ck)
deff('y=f(t)','y=1/sqrt((1-t^2)*(1-ck^2*t^2))')
intg(0,1,f)    //OK since real solution!
