It is very simple to perform this with funcrions in Octave and in the BIM and 
MSH package.
I do have some functions around to do this, if you are interested I can add 
them to the package.

These are all already in the package msh.

If you're willing to try out bim and msh  I might help in adding missing 
functions or improve the existing ones.
