Transform back from the Boltzmann variable into r.
o (float or numpy.ndarray) – Value(s) of the Boltzmann variable. If an array, it must have a shape broadcastable with t.
t (float or numpy.ndarray) – Time(s). If an array, it must have a shape broadcastable with o. Values must not be negative.
r – The return is a float if both o and t are floats. Otherwise it is an array of the shape that results from broadcasting o and t.
