Impz function fast algorithm?

Does anybody here know what is the code algorithm behind the impz function? I know it uses the recursive algorithm but how is such implemented in impz that it can get the impulse response of very high N and M orders (numerator and denominator coefficients)? I can make a script that gets the impulse response of a second order lccde but I want to know a GENERAL code that can get the impulse response of any lccdes regardless of their order.

I do not see any evidence that impz uses anything recursive.
You can look at the complete code:
type impz
