For all of you with the same question, I solved it by myselfe...
Its very easy at all, just the big amount of data is very disaponinting at the beginning.
1) You have to navigate to the directory where your data is stored
2) >> load ('xxx.neu*);
2.5) >> x = xxx.neu;
3) plot(x) or mesh(x) if you want it as a 3D Graphic
So there are just a few steps to plot this data. I think the biggest mistake of mine was the fact, that I wasn't in the right directory and Matlab can't load the file.
don't let you confuse, its just very easy at all ;)
