I know the original poster has probably solved the problem or moved on, but I
wanted to write this as a potentially helpful reference for others.
I ran into a very similar problem under different circumstances. I am calling
code written in Python/Numpy by shelling out with MATLAB's ``system`` command.
The solution that I found is described here:
http://www.mathworks.ca/matlabcentral/newsreader/view_thread/162466
To summarize, MATLAB tries to force code called from within it to use libraries
it provides. Unfortunately, these are often fairly old, and can be incompatible
with precompiled external code. Some people seem to be removing the packaged
libraries and linking them to the correct versions elsewhere, but a less
invasive approach is to modify the file
.matlab7rc.sh (in MATLAB's bin/ directory)
so that ``LDPATH_PREFIX`` points to the right directory. This is described by
user "luquesky luque," and worked for me. In my case (64-bit Linux), I changed
LDPATH_PREFIX=''
to
LDPATH_PREFIX='/usr/lib/x86_64-linux-gnu'
and saved the modified shell script to my home directory. Apparently, you can
also just save it to the project directory you're working from to avoid
user-wide changes. I think the path may not be the same for different
distributions, but you could try
find / 2>/dev/null | grep libgfortran.so.3
to verify.
