Hi!

I have to do cartesian mesh of 3d object. I have to do this in Matlab. It will be a part of FEM programme. I've read sth about Delanuay triangulation etc, but I have to do really simple disretization sth like in http://en.wikipedia.org/wiki/Regular_grid (Example of a Cartesian grid.)

I have my own solution but I want to see how people usulay done this but i can't found anythink. Does anybody know where to found some sources?

There is some good analysis software linked there. In particular at the bottom of the page. I've used both with reasonable results. If you want a professional solution then I would suggest GridGen or Pointwise.
