n |
the maximum recursive depth |
tol |
the maximum error tolerance |
The adaptint function uses Romberg's rule to calculate the
integral of the function f over the interval from a
to b. The parameter n sets the number of intervals
to use when evaluating. Additional options are passed to the
function f when evaluating.
