 ## MATLAB
 *NB* Due to licensing, the MATLAB batch connect app requires a MATLAB intallation to be present on the relevant compute nodes. The MATLAB app is therefore disabled by default, and must be enabled by setting `openondemand_matlab_partition` in e.g. `environments/site/inventory/group_vars/all/openondemand.yml` to the name of the partition where MATLAB is available.
 
-An Lmod modulefile also needs to be available on compute nodes - this is not provided by the appliance. See e.g.`roles/openondemand/tasks/rstudio_compute.yml` for an example modulefile. The path of the modulefile needs to adhere to a convention to work with the common environemnt's default batch connect form. The modulefile must be created as `matlab/< MATLAB_VERSION >`, where the version should match the `openondemand_matlab_version` variable. This variable is set to empty in the role default so must be defined in `environments/site/inventory/group_vars/all/openondemand.yml`.

 As MATLAB requires a remote desktop, the TurboVNC and Xfce Desktop packages and configuration from the  "openondemand_desktop" app will be automatically applied to nodes where the MATLAB app is enabled.
