[ff3d-users] Min/Max & read a function

[Cécile Giorla]

Hello,
I have some questions :

1) Is there a min, max function (min between 2 values and min of a 
function over the mesh) ?

2) How can I read in ff3d a function save in a vtk/vtu file ?

3) How can I read a vectoriel function save in a vtk/vtu or bb format? 
(when it was saved with save(vtk,"filename",[ux, uy, uz],M))

Thank you very much.
Cecile Giorla.
