trapz

public static double trapz(Function1D f,
                           double a,
                           double b,
                           int N)

Numerically computes the integral of the given function

Parameters:

f - the function to integrate

a - the lower limit of the integral

b - the upper limit of the integral

N - the number of points in the integral to take, must be ≥ 2.

Returns:

an approximation of the integral of ∫_a^bf(x) , dx
