  We present an algorithm to compute stabilizing minimum dwell times for
discrete-time switched linear systems without the explicit knowledge of
state-space models of their subsystems. Given a set of finite traces of state
trajectories of the subsystems that satisfies certain properties, our algorithm
involves the following tasks: first, multiple Lyapunov functions are designed
from the given data; second, a set of relevant scalars is computed from these
functions; and third, a stabilizing minimum dwell time is determined as a
function of these scalars. A numerical example is presented to demonstrate the
proposed algorithm.
