# mean

## 语法

``tsmean = mean(tsobj)``

## 说明

``tsmean = mean(tsobj)` 计算金融时间序列对象 (`tsobj`) 中所有序列的所有数据的算术均值，并在 `tsmean` 结构体中返回该值。`tsmean` 结构体包含与数据序列名称相同的字段名称。`

## 示例

1. 创建一个 `fints` 对象。

`dates_and_times = (now:now+5)'`
```dates_and_times = 1.0e+05 * 7.3840 7.3840 7.3840 7.3841 7.3841 7.3841 ```
` tsobj = fints(dates_and_times, randn(6,1))`
```Warning: FINTS is not recommended. Use TIMETABLE instead. For more information, see Convert Financial Time Series Objects (fints) to Timetables. > In fints (line 169) ```
```tsobj = desc: (none) freq: Unknown (0) {'dates: (6)'} {'times: (6)'} {'series1: (6)'} {'07-Sep-2021'} {'12:30' } {[ 0.5377]} {'08-Sep-2021'} {'12:30' } {[ 1.8339]} {'09-Sep-2021'} {'12:30' } {[ -2.2588]} {'10-Sep-2021'} {'12:30' } {[ 0.8622]} {'11-Sep-2021'} {'12:30' } {[ 0.3188]} {'12-Sep-2021'} {'12:30' } {[ -1.3077]}```
2. 使用 `log` 计算自然对数。

`tsmean = mean(tsobj)`
```Warning: FINTS is not recommended. Use TIMETABLE instead. For more information, see Convert Financial Time Series Objects (fints) to Timetables. > In fints/mean (line 22) tsmean = struct with fields: series1: 0.5648```
