first column is time, second Force and the third is acceleration. the sampling is 4000Hz and the number of NFFT is ,let us say, 4444. I'd like to compare PSDs from this software versus whatever I can cook up in matlab. I need to take the raw data (in csv files, two columns, time and amplitude of g) and run a PSD on it. I'd then like to plot a smoothed version of the PSD to make a profile curve that represents most of the data (i don't want to plot the results of the PSD, too much info).

Default for real X is 'onesided' and for complex X is 'twosided'. This MATLAB function estimates the cross power spectral density (CPSD) of two discrete-time signals, x and y, using Welch’s averaged, modified periodogram method of spectral estimation. Outlines the key points to understanding the matlab code which demonstrates various ways of visualising the frequency content of a signal at http://dadorran. power spectral density PSD?.

In an earlier post [1], I showed how to compute power spectral density (PSD) of a discrete-time signal using the Matlab function pwelch [2]. Pwelch is a useful function because it gives the correct output, and it has the option to average multiple Discrete Fourier Transforms (DFTs). The power spectral density (PSD) is intended for continuous spectra. The integral of the PSD over a given frequency band computes the average power in the signal over that frequency band.
