Calculate PSD of a signal using Welch algorithm 1.0 Description
Description: This function Calculates Power Spectral Density of signal vector X using Welch's averaged periodogram method.
X is divided into sections, then windowed by the WINDOW parameter.
The magnitude squared of the length NFFT DFTs of the sections are averaged to form Pxx. Pxx is length NFFT/2+1 for NFFT even. the default fot WINDOW is a rectangular window .
Fs is the sampling frequency which is used for scaling of plots.

Calculates windowed (over- and non-overlapping) RMS of a signal using the specified windowlength
y = rms(signal, windowlength, overlap, zeropad)
signal is a 1-D vector
windowlength is an integer length of the RMS window in samples
overlap is the number of samples to overlap adjacent windows (enter 0 to use non-overlapping windows)
zeropad is a flag for zero padding the end of your data...(0 for NO, 1 for YES)
