Remarks
The right point rule is one of the simplest numerical integration algorithms around. The interval is divided into smaller intervals, and the function value in the middle of each subinterval is taken as an approximation for the function over the entire subinterval.
This algorithm is of order 1. In each iteration, the number of points is doubled. The difference between successive approximations is taken as the estimate for the integration error.
Because the order of the algorithm is so low, use of this algorithm is not generally recommended for general use. It does provide a unique feature in that can produce absolute bounds on the value of the integral of some functions. It produces an upper bound for monotonically increasing integrands, and a lower bound for monotonically decreasing integrands. Complementary bounds are produced by the LeftPointIntegrator<T>.
