What is the difference between rnd(s) and rand('state',s)?

What is the difference, and why rand('state',sum(100*clock)) is used, and what does it mean exactly?

[Shounak Shastri]

Sorry but I cannot find anything which is named "rnd". Do you mean "rng" ? Also, please tell us the version of matlab you are using.

See the first section on this documentation page for some of the reasons why rand('state', x) is strongly discouraged. If you're using a release prior to the introduction of rng you may need that syntax, but for new code or if you're updating old code you should use rng instead.
