# Start Matlab
# ------------
# Some matlab options (see 'matlab -help' for more):
#     -nojvm        Shut off all Java support by not starting the
#                   Java virtual machine. In particular the MATLAB
#                   desktop will not be started.
#
#     -nodesktop    Do not start the MATLAB desktop. Use the current
#                   terminal for commands. The Java virtual machine
#                   will be started.
#
#     -nodisplay    Do not display any X commands. The MATLAB
#                   desktop will not be started. However, unless
#                   -nojvm is also provided the Java virtual machine
#                   will be started.
#
#     -nosplash     Do not display the splash screen during startup.
#
# Bash commands:
#     >    Pipe output to file
#     &    Background job
