CGFILL fills specified gaps in the data given an inital guess for the spectrum. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: CGFILL fills specified gaps in the data given an inital guess for the spectrum using the constrained gaussian method. At present, it only fits data described by a piecewise power-law spectrum CALL: out = obj.cgfill(pl) out = cgfill(objs, pl) INPUTS: pl - a parameter list obj(s) - input ao object(s) OUTPUTS: out - filled data series. Created 2013-02-20, M Hewitson - adapted from code writen by Curt Cutler and Ira Thorpe. Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Key | Default Value | Options | Description |
WIN | 'Hanning' |
|
The window to be applied to the data to remove the discontinuities at edges of segments. [default: taken from user prefs] Only the design parameters of the window object are used. Enter a string value containing the window name e.g. plist('Win', 'Kaiser', 'psll', 200) plist('Win', 'BH92') |
ORDERS | 0 | none | The powers of the dependent variable to fit to the data. |
P0 | 1 | none | An initial guess for the power-law coefficients. |
OFFSETS | [] | none | offset frequencies of the power-law from DC. |
WEIGHTS | [] | none | Weights for individual data bins. If empty, all bins are weighted equally. Can also be a plist for a built-in ao model |
INDICES | [] | none | List of start/stop index pairs for data to be subsituted (Nx2). Can either be an array of doubles or a cdata ao |
ITERATIONS | 3 | none | Number of times to repeat the gap-filling for smoothing |
SAMPLES | [] | none | The number of samples to truncate the correlation vector to. If empty, the full inverse correlation vector will be returned. |
NITER | 1 | none | The number of iterations to perform for the 'iterate' mode. |
MODE | 'iterate' | none | The method for deciding when to end the filling procedure:
|
PRE_FILTER | [] | none | Filter applied to data (multiplicaiton) before fitting to correct for non-powerlaw behavior in PSD.Can either be an AO, an array, or a plist for a built-in AO model |
X_VAR | 'F' | none | Key value for dependant variable for the case in which PRE_FILTER is a plist for a built-in AO model |
DEBUG | 0 |
|
Set to true to put additional objects into procinfo |
