Key | Default Value | Options | Description |
NAVS | 5 | none | The number of averages to use when calculating PSD and CPSD. |
FITPARAMS | '' | none | Parameters of the model |
INNAMES | 1 | none | Input names. Used for ssm models. |
OUTNAMES | 1 | none | Output names. Used for ssm models. |
PARAMSVALUES | 1 | none | The numerical values of the parameters. |
MODEL | '' | none | An array of matrix models |
INPUT | '' | none | The input signal to the system. It should be a matrix of AOs, the rows denoting the channels, and the columns the number of experiments. An array of matrix objects is also accepted. |
PINV | 1 |
|
Use the Penrose-Moore pseudoinverse |
TOL | [] | none | Tolerance for the Penrose-Moore pseudoinverse |
DIFFSTEP | [] | none | Numerical differentiation step for ssm models |
NGRID | [] | none | Number of points in the grid to compute the optimal differentiation step for ssm models |
STEPRANGES | [] | none | An array with upper and lower values for the parameters ranges. To be used to compute the optimal differentiation step for ssm models. |
LOG PARAMETERS | [] | none | An array with upper and lower values for the parameters ranges. To be used to compute the optimal differentiation step for ssm models. |
FREQUENCIES | [] | none | The frequencies to perform the analysis. |
FSOUT | [] | none | Resampling. |
F1 | [] | none | Initial frequency for the analysis. |
F2 | [] | none | Final frequency for the analysis. |
NOISE SCALE | 'PSD' |
|
Select the way to handle the noise/weight data. Can use the PSD/CPSD or the LPSD/CLPSD functions. |
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 | 'BH92' |
|
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, N | 0 |
|
The order of segment detrending:
|
TIMES, 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:
