Method ao/ppsd
ppsd.m
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: PPSD makes power spectral density estimates of the
time-series objects in the input analysis objects
by estimating ARMA models coefficients. The coefficients
are stored in the procinfo plist of the output objects.
CALL: bs = ppsd(a1,a2,a3,...,pl)
bs = ppsd(as,pl)
bs = as.ppsd(pl)
INPUTS: aN - input analysis objects
as - input analysis objects array
pl - input parameter list
OUTPUTS: bs - array of analysis objects, one for each input

Description |
METHOD |
'AR' |
|
Model type to use and estimate its coefficients. |
ORDER |
[] |
none |
Order of the applied filter. If the method chosen is 'ARMA', then a vector of 1x2 size must be provided containing the orders AR and MA models. (example: [ p q ]). - If no order is specified, then p = q = length(X) - 1;
|
TIMES |
[] |
none |
The time range to analyze. If not empty, sets the time interval to operate on. |
SPLIT |
[] |
none |
The time range to analyze. If not empty, sets the timeinterval to operate on. As in ao/split, the interval can be specifiedby:- a vector of doubles
- a timespan object
- a cellarray of time strings
- a vector of time objects
|
SCALE |
'PSD' |
|
The scaling of output. Choose from:- PSD - Power Spectral Density
- ASD - Amplitude (linear) Spectral Density
- PS - Power Spectrum
- AS - Amplitude (linear) Spectrum
