.SH DESCRIPTION
given three vectors \fV(x,f,d)\fR defining a spline function
(see \fVsplin\fR) with \fVfi=S(xi), di = S'(xi)\fR this function
evaluates \fVS\fR (resp. \fVS', S'', S'''\fR) at \fVxd(i)\fR.

x
: vector of \fVxi (x(1) < x(2) < ...)\fR
.TP
f
: vector of \fVS(xi)\fR
.TP
d
: vector of \fVS'(xi)\fR
.TP
f0
: vector \fV[S(xd(1),S(xd(2)),S(xd(3)),...]\fR
.TP
