| 1 | Data | Data. An exception is raised if Data vector is complex. |
| 2 | Alpha | Defines the percent of value excluded from mean calculation. If Alpha parameter is omitted, the default value 0.05 is used (meaning highest 2.5% and lowest 2.5% of data will be excluded). Alpha paramater must lie on the interval [0,1) otherwise an exception is raised. |
