INTERP(G)                      Scilab Function                      INTERP(G)
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)),...]
