[Matplotlib-users] PSD amplitude disparity

2010-03-02 Thread Dunx
Hi, I know about the difference between pylab.psd and mlab.psd, but in theory the only difference between the returned values is: pylab.psd = 10*log10(mlab.psd) Except this is not true, there is noticeable difference: pylab.psd = 23.4962 (all these pylab.psd values are read from graph)
