| Key | Default Value | Options | Description |
| KDES | 100 | none | The desired number of averages. |
| JDES | 1000 | none | The desired number of spectral frequencies to compute. |
| LMIN | 0 | none | The minimum segment length. |
| 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 | 0 |
|
The order of segment detrending:
|
| 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:
|
| NAVS | 1 | none | |
| F1 | [] | none | Initial frequency for the analysis |
| F2 | [] | none | Final frequency for the analysis |
| FITPARAMAS | '' | none | Parameters of the model |
| MODEL | '' | none | An array of matrix models |
| NOISE | '' | none | An array of matrices with the cross-spectrum matrices |
| BUILT-IN | '' | none | Symbolic models of the system as a string of built-in models |
| 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 |
| DIFFSTEP | [] | none | Numerical differentiation step for ssm models |
