+ -- Function File: PP = catmullrom( X, F, V)
+     Returns the piecewise polynomial form of the Catmull-Rom cubic
+     spline interpolating F at the points X.  If the input V is
+     supplied it will be interpreted as the values of the tangents at
+     the extremals, if it is missing, the values will be computed from
+     the data via one-sided finite difference formulas. See the
+     wikipedia page for "Cubic Hermite spline" for a description of the
+     algorithm.

+ -- Function File: PP =  csape (X, Y, COND, VALC)
+     cubic spline interpolation with various end conditions.  creates
+     the pp-form of the cubic spline.
+
+     the following end conditions as given in COND are possible.
+    'complete'
+          match slopes at first and last point as given in VALC
+
+    'not-a-knot'
+          third derivatives are continuous at the second and second
+          last point
+
+    'periodic'
+          match first and second derivative of first and last point
+
+    'second'
+          match second derivative at first and last point as given in
+          VALC
+
+    'variational'
+          set second derivative at first and last point to zero
+          (natural cubic spline)
