trapz performs numerical integration via the trapezoidal method. This method approximates the integration over an interval by breaking the area down into trapezoids with more easily computable areas.

Finding approximate the integral using the composite trapezoidal rule, of a function f (x) = cos (x): format long. eps_step = 1e-5; N = 20; a = 0; b = 10; h = b - a; ctrap = 0.5*(cos(a) + cos(b))*h; for i=1:N.
The composite trapezoidal rule. The integral \( \int_a^b f(x)dx \) may be interpreted as the area between the \( x \) axis and the graph \( y=f(x) \) of the integrand. Figure 7 illustrates this area for the choice . Computing the integral \( \int_0^1f(t)dt \) amounts to computing the area of the hatched region.
Initial Requirements. We start with the single interval [ a, b ], set h = b - a, and let T 0 = ½ (f ( a) + f ( b )) h. Iteration Process. For n = 1, 2, ..., we divide the interval [ a, b] into 2 n sub-intervals (and therefore h = (b - a)/2 n) and we set. Halting Conditions. There are two conditions which may cause the iteration process to halt:
