Why does Matlab set the LD_LIBRARA_PATH environment variable of the shell in which it executes "system" commands on Linux?
I can understand setting this for matlab's own use, but for commands executed on the system, surely you want them to be executed using the system libraries. I only discovered this because I was finding my commands failing with cryptic errors referencing paths in the Matlab installation directory.
Is there any way to control the behviour?

MATLAB uses system() to invoke its own utilities such as mex(), so it needs to have the right LD_LIBRARY_PATH set up for those, and those utilities need to be accessible to scripts that the user invokes.
