If you can't find an application on a Purdue IT-supported Linux host, try using the Lmod environment module system. This command will show you the software available for loading using Lmod:
module avail
You will see something like this:

By default, no modules are loaded at login or when a terminal/console/shell is opened. To use a specific application:
module load matlab
This will load the default version of Matlab. Those are noted by the (D) next to them in the module avail command.
You can also load a specific version of an application, too:
module load matlab/R2015a
This will unload the version of Matlab currently loaded if it is not R2015a.
NOTE: loading a module does not start the associated software. It only modifies your environment so you can then run the associated command(s) for that software.
Also, lmod modifies your shell environment. Previously, you might have used an explicit path to run Matlab, like:
/usr/opt/bin/matlab -nodisplay < my_run.m
This is a perfectly reasonable and excellent way to do things. However, there is no /usr/opt/bin on systems that use lmod. Instead, you can just do:
matlab -nodisplay < my_run.m
You could use an explicit path for a program by doing something like:
which matlab
However, that path might change over time, so we would recommend against it when using lmod.
More information about Lmod can be found in the project documentation.
If you have problems with lmod commands not being found:
You can determine which shell you're using by running:
echo "$SHELL"
If you are using bash, it is recommended you add the lines below to the top of ~/.bashrc :
if [ -f /etc/bashrc ]; then
. /etc/bashrc
elif [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
You might need to make sure the terminal/shell is a 'login' shell. First, look at the top of the terminal/shell window. If the title of the window is 'Terminal', see the Terminal instructions. If the title includes 'Konsole', see the Konsole instructions.
Under Edit-->Preferences there should be a choice to open the terminal/shell as a 'login' shell. Select "Run command as login shell", then close that terminal and open a new one. The lmod commands should now be properly sourced and available.
Click on the Settings menu item and select Manage Profiles...
If there is only one profile listed and it is marked as read-only, a new profile must be created. Click on the New button on the left side.
If the existing default profile is not read-only, click on the Edit button on the left side instead. Under the profile name check the box labeled Default profile. Add the "-l" flag /bin/bash (or another shell like tcsh or zsh). Next, click the Apply button.
Click on the OK button, then close that terminal and open a new one. The lmod commands should now be properly sourced and available.
