I have 296500*36 data in matlab for EEG signal. I want to plot it and then do the Power Spectral density using welch for 30 second windows. Sampling frequency is 250 Hz. I would appreciate it if someone can help. Thank you.

You can use pwelch for finding the power spectral density of the signal.
For example,
pwelch(x,250*30, [],[],250);
where x is the input signal, 250*30 is the window length and 250 is the sampling frequency.
