NAME

6       c_ftcurvp - 1D interpolation for periodic functions

FUNCTION PROTOTYPE

9       int  c_ftcurvp  (int,  float  [], float [], float, int, float [], float
10       []);

SYNOPSIS

13       int c_ftcurvp (n, xi, yi, p, m, xo, yo);
14

DESCRIPTION

16       n           The number of input data points. (n > 1)
17
18       xi          An array containing the abscissae for the input function.
19
20       yi          An array containing the input functional  values  (y(k)  is
21                   the functional value at x(k) for k=0,n).
22
23       p           The period of the function; p must not be less than xi[n-1]
24                   - xi[0].
25
26       m           The number of desired interpolated points.
27
28       xo          An array containing the abscissae for the interpolated val‐
29                   ues.
30
31       yo          An  array  containing  the  interpolated  functional values
32                   (yo(k) is the functional value at xo(k) for k=0,n).
33

RETURN VALUE

35       c_ftcurvp returns an error value as per:
36
37       = 0 -- no error.
38       = 1 -- if n is less than 2.
39       = 2 -- if the period is strictly less than the span of the abscissae.
40

USAGE

42       c_ftcurvp is called after all of the desired values for control parame‐
43       ters  have  been set using the procedures c_ftseti, c_ftsetr, c_ftsetc.
44       Control parameters that apply to c_ftcurvp are: sig.
45
