delip            Scilab Group            Scilab Function              delip
NAME
   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 :
  
 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 for
  each entry of x.
  
EXAMPLE
 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!
