The seed is not changing when I close the Matlab and open a new one. The seed is always being set as 0. How can I fix this?

Your question is a bit on the vague end - but I'll guess that you're asking about the seed for the random number generator...
If that's the case you should take a look at the help for rand, or look for the documentation pages "Updating Your Random Number Generator Syntax". From the former there is a link towards the latter, the latter describes in detail how to randomize the start of the random number sequence...

"This is not supposed to happen. The seed should change when I close and open a new Matlab window."
Yes, it is supposed to happen. This is exactly the documented behavior. In fact this is such a common topic that there is a whole page devoted to explaining this:
That page also explains how to get different random numbers, and is easy to find using any internet search engine.
