WriteToVTK

This writes a 3D matrix to a VTK file. An old text-based format is used because it is easy to write to. This may result in very large file sizes.

The matrix is normalised, kind of. Not sure why I did that; it might not be needed. The code is very short so feel free to experiment!

Usage:

WriteToVTK(matrix, filename)

Example:

m = reshape(magic(6), [3 3 4]);
WriteToVTK(m, 'magic.vtk');
