No, and you probably shouldn't be doing the latter if you can avoid it.

No. See the page linked in the Note at the top of the Description section
for a more thorough explanation of what rng('default') is doing and why we
discourage the rand(string, seedValue) and randn(string, seedValue)
That page also lists the RNG equivalent for "rand('state', 0)" if you need
to reproduce results from older releases of MATLAB.
