A more flexible solution is provided. The Quick Sheets are of no value. Interpolaqtion at any valid point is possible here.

Some of the Quick Sheet was copied into MathCad and re-programed along with my FFTe and the results compared. The Quick Sheet method suffers from Gibbs' phenomenum at the origin.
