How can I save a matrix as .vox or .raw file

Can anybody help me to save a 3D matrix as a voxel model (.vox format) or raw image (.raw format)? My matrix may contain complex numbers.

Hi Nima

did you found the answer?

I have same problem.

I don't know what the .vox format is and @nima didn't say. Likewise there is no standard "raw" format. Anyone can pretty much define it however they want and again @nima didn't say. So you could use frpintf() to write out slice-by-slice the real parts, and then follow that with slice-by-slice of the imaginary parts, or whatever you want. So, @MSHR you should start your own question and tell us the exact format you want, like what voxel values in what order. And if you want the real and complex together voxel-by-voxel, or if you want the whole volume's real part first followed by the whole volume's imaginary part.
