Matlab command batch “matlab -batch” is useful for running Matlab scripts from the command line. When using “stdout” text output from Matlab, especially if only a single line is expected, there may be extraneous text output from Matlab with regard to licensing. A command example is prereleases like:

matlab -batch "disp(matlabroot)"

outputs to stdout:

    Prerelease License -- for engineering feedback and testing
	purposes only. Not for sale.

A workaround for this in shell scripts is like:

set -e  # stop on error

r=$(matlab -batch "disp(matlabroot)" | tail -n1)

cd ${r}
# and so on
