# Running Matlab Interactively

On the Yens, Matlab is available via the `module` command.

Several versions of Matlab are installed and the default version is designated with `(D)`:

Terminal Command

```
module avail matlab
```

Terminal Output

```
-------------------------------- Global Aliases --------------------------------


---------------------------- /software/modules/Core ----------------------------
   matlab/R2018a    matlab/R2019b    matlab/R2022a        matlab/R2024a
   matlab/R2018b    matlab/R2021b    matlab/R2022b (D)

  Where:
   D:  Default Module
```

## Loading a Matlab Module

To load the default Matlab module (for example, `matlab/R2022b`), run:

Yen Terminal Input

```
ml matlab
```

Note

`ml` is a shorthand for `module load`. Learn more about modules [here](/_getting_started/modules).

If you want to load a specific Matlab version instead, specify it directly:

Yen Terminal Input

```
ml matlab/R2024a
```

## Starting an Interactive Matlab Session

You can start the Matlab interactive console by typing `matlab`:

Yen Terminal Input

```
matlab
```

### Example Output

### Exiting Matlab

To exit matlab simply type:

Matlab Input

```
exit
```

## Running Matlab Scripts

Create a simple test script named `hello_world.m`:

hello_world.m

```
function hello()
    fprintf('Hello!');
end
```

To run this script non-interactively (without the desktop environment), use:

Terminal Input

```
matlab -batch "hello()"
```

Use Batch Mode for Running Scripts

The `-batch` option runs Matlab in a batch mode, which is useful when working on a remote server or over SSH where graphical interfaces may not be available or convenient.

## Use Graphical Matlab Interface on Jupyter

Start a full Matlab GUI from [JupyterHub](/_getting_started/jupyter/) by navigating to Launcher / Notebook section.
