# mean

Arithmetic average

`mean` is not recommended. Use `timetable` instead. For more information, see Convert Financial Time Series Objects fints to Timetables.

## Syntax

``tsmean = mean(tsobj)``

## Description

example

````tsmean = mean(tsobj)` computes the arithmetic mean of all data in all series in the financial time series object (`tsobj`) and returns it in a structure `tsmean`. The `tsmean` structure contains field name(s) identical to the data series name(s).```

## Examples

collapse all

1. Create a `fints` object.

`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. Calculate the natural logarithm using `log`.

`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```

## Input Arguments

collapse all

Financial time series object, specified as a `fints` object.

Data Types: `object`

## Output Arguments

collapse all

Arithmetic mean of all data in all series in the financial time series object, returned as a structure.
