AFL% eo_gettrs([...]);| Argument | Description |
|---|---|
... |
Optional list of arrays |
A one-dimensional table-like array with rows for all given arrays and attributes (name,tdim,t0,dt,tMin,tMax). If no array is given as argument, the operator considers all temporally referenced arrays. Result attributes are described below.
| Attribute | Description |
