c_ftcurvpi – calculate integrals for periodic functions
Function Prototype
int c_ftcurvpi (float, float, float, int, float [], float [], float *);Synopsis
int c_ftcurvpi (xl, xr, p, m, xi, yi, integral);Description
- xl
- The lower limit of the integration.
- xr
- The upper limit of the integration.
- p
- The period of the function; p must not be less than xi[n-1] – xi[0].
- m
- The number of input data points. (N > 1)
- xi
- An array containing the abscissae for the input function.
- yi
- An array containing the functional values of the input function (y(k) is the functional value at x(k) for k=0,n).
- integral
- The integral of the function from xl to xr is given by *integral.
Return Value
c_ftcurvpi 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.
Usage
c_ftcurvpi 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_ftcurvpi are: sig.Access
