Code completion for toolbox functions

Hi

I installed the Symbolic Math Toolbox over an existing Matlab 2012a installation and I noticed there is no auto-completion support when typing functions from this toolbox (laplace,ilaplace,ztrans,iztrans etc).

Still, the functions work when called.

I am using a 64bit Arch Linux OS, therefore this might be the root of the problem.

Any suggestion on how to enable the code-completion support?

Thanks

[edit]

The pathdef.m file from /opt/MATLAB/.../toolbox/local contains the following lines

matlabroot,'/toolbox/symbolic/symbolic:', ...

matlabroot,'/toolbox/symbolic/symbolicdemos:', ...

Have you attempted the tried & true RMRM method (Restart MATLAB & Restart Machine)?
