I have a row vector of 4 seconds VAG signals, how can I find the mean squared values of the signal in fixed duration of 5ms each?

Are you talking about root mean square (RMS) value?
If yes, then you can directly find the value using following Matlab function
m_value=rms(data);

Thank you so much, that is the function I am looking for. Then how about dividing the signal into 5ms per segment?
