Saving Device Objects to a MAT-File

You can save a device object to a MAT-file just as you would any workspace variable -- using the save command. For example, to save the analog input object ai and the variable time defined in the preceding section to the MAT-file myai1.mat:

```
save myai1 ai time
```

Read-only property values are not saved. Therefore, read-only properties use their default values when you load the device object into the MATLAB workspace. To determine if a property is read-only, use the propinfo function or examine the property reference pages.

Loading the Device Object

To load a device object that was saved to a MAT-file into the MATLAB workspace, use the load command. For example, to load ai and time from MAT-file myai1.mat:

```
load myai1
```
