c_ftcurvp - 1D interpolation for periodic functions
int c_ftcurvp (int, float [], float [], float, int, float [], float []);
int c_ftcurvp (n, xi, yi, p, m, xo, yo);
- n
- The number of input data points. (n > 1)
- xi
- An array containing the abscissae for the input
function.
- yi
- An array containing the input functional values (y(k) is
the functional value at x(k) for k=0,n).
- p
- The period of the function; p must not be less than xi[n-1]
- xi[0].
- m
- The number of desired interpolated points.
- xo
- An array containing the abscissae for the interpolated
values.
- yo
- An array containing the interpolated functional values
(yo(k) is the functional value at xo(k) for k=0,n).
c_ftcurvp returns an error value as per:
= 0 -- no error.
= 1 -- if n is less than 2.
= 2 -- if the period is strictly less than the span of the abscissae.
c_ftcurvp is called after all of the desired values for control parameters have
been set using the procedures c_ftseti, c_ftsetr, c_ftsetc. Control parameters
that apply to c_ftcurvp are: sig.
To use c_ftcurvp, load the NCAR Graphics library ngmath.
fitgrid_params, c_ftseti, c_ftsetr, c_ftsetc.
