Method ao/psdconf

  PSDCONF Calculates confidence levels and variance for psd
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: PSDCONF Input a spectrum estimated with psd or lpsd (Welch's
  Overlapped Segment Averaging Method) and calculates confidence levels and
  variance for the spectrum.
 
  CALL:         [lcl,ucl] = psdconf(a,pl)
                [lcl,ucl,var] = psdconf(a,pl)
 
  INPUTS:
                a  -  input analysis objects containing power spectral
                      densities calculated with psd or lpsd.
                pl  - input parameter list
 
  OUTPUTS:                
                lcl - lower confidence level
                ucl - upper confidence level
                var - expected spectrum variance
 
 
               If the last input argument is a parameter list (plist).
               The following parameters are recognised.
 
  
  NOTE1: PSDCONF checks the navs field to distinguish between psd and lpsd
  power spectra. If a.data.navs is NaN then it assumes to dealing with lpsd
  power spectrum at input.
 
  NOTE2: Copied directly from MATLAB chi2conf function (Signal Processing
  Toolbox) and extended to do degrees of fredom calculation, variance
  calculation, to input AOs and to input plist.
