c_ftcurvi – calculate integrals
Function Prototype
int c_ftcurvi (float, float, int, float [], float [], float *);Synopsis
int c_ftcurvi (xl, xr, n, xi, yi, integral);Description
- xl
- The lower limit of the integration.
- xr
- The upper limit of the integration.
- n
- 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_ftcurvi returns an error value as per: = 0 — no error.
= 1 — if n is less than 2.
= 2 — if X values are not strictly increasing.
Usage
c_ftcurvi 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_ftcurvi are: sig, sl1, sln, sf1.Access
