INTERP            Scilab Group            Scilab Function            INTERP
NAME
   interp - interpolation
  
CALLING SEQUENCE
 [f0 [,f1 [,f2 [,f3]]]]=interp(xd,x,f,d)
PARAMETERS
 xd         : real vector
            
 x,f,d      : real vectors from spline
            
 fi         : vectors (derivatives)
            
DESCRIPTION
   given three vectors (x,f,d) defining a spline function (see splin) with
  fi=S(xi), di = S'(xi) this function evaluates S (resp. S', S'', S''') at
  xd(i).
  
 x          : vector of xi  (x(1) < x(2) < ...)
            
 f          : vector of S(xi)
            
 d          : vector of S'(xi)
            
 f0         : vector [S(xd(1),S(xd(2)),S(xd(3)),...]
            
 f(1 2 3)   : vector of first, second, third derivative of S at
            xd=[xd(1),xd(2),...] i.e.
            
           f1 = [S'(xd(1)),S'(xd(2)),...]
            
           f2 = [S''(xd(1)),S''(xd(2)),...]
