MATLAB file icons on linux

Hello there,

I have installed MATLAB R2011B on a Linux laptop (Kubuntu 11.10). I managed to create a launcher for the application and I also managed to locate the MATLAB icon. However, the m-files I create get either a TeX or a C icon in my browsers (Dolphin and Krusader) instead of the usual icon I am used to under Windows. The icon I am looking for is the icon you see in MATLAB for each MATLAB script (looks like a white paper with some gray lines and the MATLAB icon on the upper-left corner). Where can I find this icon. I would like to associate all m-files on my laptop with that icon.

Thanks in advance!
