NAME
       CURV2 - 1D interpolation for non-periodic functions.


SYNOPSIS
       FUNCTION CURV2 (T, N, X, Y, YP, SIGMA)

       This  function  interpolates  a  value  at a specified point using a spline under tension.
       CURV1 must be called prior to calling CURV2, and the values thus obtained used as input to
       CURV2. CURV2 returns the interpolated function value at the X-coordinate specified.


DESCRIPTION
       T           (real,  input)  The  abscissa  for  which  an  interpolated  function value is
                   desired.

       N           (integer, input) The number of input data values. (N > 1)

       X           (real, input) An array containing the abscissae for the input function.

       Y           (real, input) An array containing the functional values of the input  data  --
                   Y(K) is the functional value at X(K) for K=1,N.

       YP          (real,  input)  Contains  values  for  the second derivative (as calculated by
                   CURV1).

       SIGMA       (real, input) Tension factor. Values near zero result in a cubic spline; large
                   values (e.g. 50) result in nearly a polygonal line. A typical value is 1.


RETURN VALUE
       CURV2 returns the interpolated value at the specified point T.


ACCESS
       To use CURV2, load the NCAR Graphics library ngmath.
