Mathematically, the algorithm is
lower_bound + floor((upper_bound - lower_bound) * rand(size_to_generate))
Taking into account that rand() cannot generate exactly 0 or exactly 1.
This is not necessarily the MATLB implementation; the actual MATLAB implementation might try to compensate for the fact that binary does not map exactly onto factions.

We don't distribute the source code for the randi built-in function. If you want to see it, start here.
