CRBOUND computes the inverse of the Fisher Matrix %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: CRBOUND computes the Cramer-Rao lowe bound for parametric model given the input signals and the noise. The method accepts 2D (2 input/2 output) models and 1D models (1 input/1 output) and (2 input/1 output) CALL: bs = crbound(in,noise,pl) INPUTS: in - analysis objects with input signals to the system (x1) if 1 input (x2) if 2 input noise - analysis objects with measured noise (x1) if 1 input: S11 (x4) if 2 input: (S11,S12,S21,S22) model - symbolic model (smodel) containing the evaluated transfer function models (x1) if 1 input/1 output (x2) if 2 input/1 output (x4) if 2 input/2 output pl - parameter list OUTPUTS: bs - covariance matrix AO Parameters Description VERSION: $Id: crbound.m,v 1.15 2012/01/23 14:19:03 ingo Exp $ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Key | Default Value | Options | Description |
NFFT | -1 | none | The number of samples in each fft [default: length of input data]. A string value containing the variable 'fs' can also be used, e.g., plist('Nfft', '2*fs') |
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') |
PSLL | 200 | none | The peak sidelobe level for Kaiser windows. Note: it is ignored for all other windows |
OLAP | -1 | none | The segment percent overlap [-1 == take from window function] |
ORDER | 0 |
|
The order of segment detrending:
|
NAVS | 1 | none | Force number of averages. If set, and if Nfft was set to 0 or -1, the number of points for each window will be calculated to match the request. |
TIMES | [] | none | The time range to analyze. If not empty, sets the time interval to operate on. As in ao/split, the interval can be specified by:
|
SPLIT | [] | none | The time range to analyze. If not empty, sets the time interval to operate on. As in ao/split, the interval can be specified by:
|
PARAMS | '' | none | Parameters of the model |
MODELS | '' | none | Symbolic models of the system |
FREQUENCIES | '' | none | Array of start/sop frequencies where the analysis is performed |
PINV | 1 |
|
Use the Penrose-Moore pseudoinverse |
TOL | [] | none | Tolerance for the Penrose-Moore pseudoinverse |
