Chemistry: Are there specialized MATLAB tools (including 3d-party developers)?

http://www.mathworks.com/products/matlab/description4.html -- here the fullerene nolecule is depictured as an example. But have MATLAB tools for (at least) visualization of complex molecules as used in chemical model with balls and sticks)? Also may be exists a collection of m-files for these purposes?

And perhaps this collection (tool) have tools to export/import chemical description from MOPAC, GAUSSIAN and HyperChem languages (formats)?
