In some systems (here, it was 64-bit Matlab on 64-bit Ubuntu 12.10) you may find an error about the version of libstdc++ being wrong. E.g. when using the system() or unix()commands.
Here’s what worked for me.
1) cd /usr/local/MATLAB/R2013a/sys/os/glnxa64
2) sudo mkdir obsolete
3) sudo mv libstdc* obsolete/
4) sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc* ./
The specific error this fixed for me was calling gnucap from Matlab. I would get the error:
gnucap: /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.15′ not found (required by gnucap)
when running in Matlab
unix('gnucap -b foo.net')
or
system('gnucap -b foo.net')
