export variables to vtk or similar

[Fabian Braennstroem]

Hi,

    I would like to export variables in a mat file to some
    other format like vtk, silo or ensight.

    The structure of the mat file looks like this:

    vx          vz          y mg          vy          x           z

   Where vx, vz, vy and mg are scalars and x,z,y are the corresponding 
positions.
   All variables have the same structure:

octave:3> size(vx)
ans =

    61   256    60

octave:4> size(x)
ans =

    61   256    60


Does anyone have an idea, how to export these 3D data to some common cfd 
format? Would be nice, if someone has an idea :-)


Greetings!
 Fabian
