NAME
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
To use c_ftcurvi, load the NCAR Graphics library ngmath.
