Adaptive Clenshaw-Curtis Quadrature
Adaptive Clenshaw-Curtis Quadrature.
quadcc(f, a, b, tol = .Machine$double.eps^0.5, ...)
f |
integrand as function, may have singularities at the endpoints. |
a, b |
endpoints of the integration interval. |
tol |
relative tolerence. |
... |
Additional parameters to be passed to the function |
Adaptive version of the Clenshaw-Curtis quadrature formula with an (4, 8)-point erroe term.
List with two components, value the value of the integral and
the relative error error.
