Code up in VBA the spline routines from numerical recipes. These are
actually free and available online at: http://www.nr.com/

Is there any way in Excel or VBA to do a spline approximation to test data
that do not follow any polynomial shape? I mean, I have data points and I
want to approximate (i.e., not necessarily pass through the points) that data
with a spline curve.
Thanks.
