The recursive adaptiveQuadrature() function is initially called with the maximum number of recursion levels to perform, so adaptiveQuadrature() should decrement numberOfRecursions at each recursion level. When adaptiveQuadrature() needs to recurse, it splits the interval in two, calculates the integral for each half by calling itself recursively, and adds the result from each half. However, it then ignores this result and returns NAN because it is checking a stale quadKG.absoluteError value. Rearrange the code to avoid that.
