function [I] = Romberg(func,a,b,tol,kmax)
Romberg integrates function "func" of one variable and nonsingular
from "a" to "b" with tolerance "tol" and maximum order of "kmax".
0 < tol < 1 & kmax > 0. Using Romberg integration.
I = Romberg(@func,a,b,tol,kmax)
I = Romberg(@func,a,b,tol)ss,ssdefault kmax = 15
I = Romberg(@func,a,b)ss,ssdefault tol = 1e-10ss,ssdefault kmax = 15
e.g.
I = Romberg(@sin,0,pi)
I = 2.000000000000000
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function [] = RombergDisp(func,a,b,k)
Romberg integrates function "func" of one variable and nonsingular
from "a" to "b" with order of "k" and displays all results.
k >= 0. Using Romberg integration.
I = RombergDisp(@func,a,b,k)
e.g.
RombergDisp(@sin,0,pi,2)
0.000000000000000ss
