In the Ruby version of gammaInc_Q, near the end there is a few lines

(n-1).step(0, -1) do |j|

t = h * j

sum += f0[t] + hh * df0[t]

end

The last iteration produces a value of j of 0, which means t is zero but df0[t] is not a number

as it requires the calculation of 0**a2. I just changed the iterator to (n-1).step(1, -1) do |j|

and it seems to give the correct result.
