Romberg array Calculator
Calculates the Romberg array produced by applying Richardson’s extrapolation procedure, which forms the basis of the Romberg Method.
|The Romberg integration Rnn can be rapidly converged with the increase in n.|
It is calculated by increasing the number of partitions to double from 2 to N=2n.
In the case of non-analytic at endpoints of f(x), you can calculate by Midpoint rule.
In the case of a periodic function, you can calculate by Non-linear substitution in x.
