## Useful Commands {#useful-commands}
| Command | Description |
|------------------------|-------------------------------------------------------------|
| `desktop` | Open the Matlab Desktop |
| `workspace` | Open the Workspace |
| `who` | List all variables in the workspace |
| `edit <filename>` | Edit the file using Matlab Desktop (usefully for debugging) |
| `help <function>` | |
| `doc <function>` | |
| `checkcode <filename>` | Check Matlab code files for possible problems |
| `preferences` | Open Matlab preferences |
## Tips {#tips}
- Folder that starts with a `+` are automatically added to the path.
It is useful to add function inside such folder.
Then the function is accessible with `folder.function`.
## Figures {#figures}
### Bode Plot {#bode-plot}
## Snippets {#snippets}
### Do not show legend for one plot {#do-not-show-legend-for-one-plot}
```matlab
figure;
hold on;
plot(x, y1, 'DisplayName, 'lengendname');
plot(x, y2, 'HandleVisibility', 'off');
hold off;
legend('Location', 'northeast');
```
## Linux Installation {#linux-installation}
If a single user is using the Matlab installation on the machine:
```bash
sudo chown -R $LOGNAME: /usr/local/MATLAB/R2017b
```
Then, Toolboxes can be installed by the user without any problem.
To install Toolboxes, the best is to Download the Matlab installer from mathworks and just select the wanted toolboxes.
## Used Toolboxes {#used-toolboxes}
Nice functions:
- <https://github.com/jmrplens/SetFigPaper>
- <https://github.com/altmany/export%5Ffig>
- Matlab's `exportgraphics`
- `vfit3` ([link](https://www.sintef.no/projectweb/vectorfitting/)): used to identify transfer functions
## Debug Scripts {#debug-scripts}
