)
inlinestatic
Note
This version overloaded to not require arguments passed in for function evaluation counts or error estimates.
Parameters
fthe integrand (invocable with a single scalar)
alower integral bound
bupper integral bound
targetAbsoluteErrordesired absolute error in the result
Returns
The value of the integral.
