Write to a Diary File

To keep an activity log of your MATLAB^®session, use thediaryfunction.diarycreates a verbatim copy of your MATLAB session in a disk file (excluding graphics).

For example, if you have the arrayAin your workspace,

A = [ 1 2 3 4; 5 6 7 8 ];

execute these commands at the MATLAB prompt to export this array usingdiary:

Turn on thediaryfunction. Optionally, you can name the output filediarycreates:
```
diary my_data.out
```
Display the contents of the array you want to export. This example displays the arrayA. You could also display a cell array or other MATLAB class:
```
A = 1 2 3 4 5 6 7 8
```
Turn off thediaryfunction:
```
日记了
```
diarycreates the filemy_data.outand records all the commands executed in the MATLAB session until you turn it off:
```
A = 1 2 3 4 5 6 7 8 diary off
```
Open thediaryfilemy_data.outin a text editor and remove the extraneous text, if desired.
