You will find the examples in the folder SYSTEMML_INSTALL_PATH/BRAHMS/support/example/995. The processes described in these tutorials are installed with the Namespace that comes with the BRAHMS release. To run the tutorials, either navigate to this folder in Matlab, or add it to your Matlab path, then just run the scripts. You will have to specify the language you want to use as an argument to each script; to see how to do this, run them without arguments.
