delip - elliptic integral

### Calling Sequence

  `[r]=delip(x,ck)`

### Parameters

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

### Description

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` .

### Examples

    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!
