## 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_fig>
-   Matlab's `exportgraphics`
-   `vfit3` ([link](https://www.sintef.no/projectweb/vectorfitting/)): used to identify transfer functions
