USAGE:<br />q = spectral(x,dt,win,Wn,ftype,n)<br ...

q = spectral by alex sanchez(x, dt, win, Wn, ftype, n)
[psdf, f] = spectral 1.0(x, dt, win, Wn, ftype, n)
[psdf, psdfc, f] = spectral [spectral1.0.exe](x, dt, win, Wn, ftype, n)
Calculates the spectrum for x using the periodogram method. If a window other than boxcar is used than the method is refered to as modified periodogram method. The confidence intervals are calculated using the inverse of chi-square CDF. Also includes a filter option using the butterworth filter to see the effect of the filter on the spectrum
x - Time series, [vector]
dt - Sampling Rate, [scalar]
win - Window, one of:
'hanning', 'hamming', 'boxcar'
Nb - Band Averaging, number of bands to average
P - Probability for confidence intervals
Wn - Cut-Off frequencies, used for filtering
ftype - Type of filter, 'high', 'low' or 'stop'
ncb - Number of coefficients to use in
the Butterworth filter
q - structure with the following fields:
xp - detrended x
f = Frequencies
T - Periods
m - Magnitude
a - Amplitude
s - power spectrum, Sxx(win), [Power]
psdw - Power spectral - 0MB density, Pxx(win), [Power/rad/sample]
psdf - Power spectral 1.0 Density, Pxx(f), [Power/sample-freq]
psdT - Power Spectral Density, Pxx(T), [Power*time-unit]
conf - Upper and Lower Confidence Interval multiplication
factors using chi-squared approach
