Matlab pwelch function

WebDescription. pxx = pwelch (x) returns the power spectral density (PSD) estimate, pxx , of the input signal, x, found using Welch's overlapped segment averaging estimator. When x is a vector, it is treated as a single channel. When x is a matrix, the PSD is computed independently for each column and stored in the corresponding column of pxx. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/pwelch.html
