COHERE estimates the coherence between time-series objects in a collection object. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: COHERE estimates the coherence between time-series objects in a collection object. CALL: out = cohere(in, pl); Note: this is just a wrapper of ao/cohere. Each couple of AOs in the collection is passed to ao/cohere with the input plist. INPUTS: in - input collection objects pl - parameter list OUTPUTS: out - output collection objects Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

| Key | Default Value | Options | Description |
| cohere | |||
| 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:
|
| 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. |
| DROP WINDOW SAMPLES | 1 |
|
Drop the recommended (by the window) number of samples of the final computed spectral series. |
| 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:
|
| TYPE | 'C' |
|
type of output scaling. Choose from:
