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.
