Rotating a 3D CT Reconstruction Cube About an Axis

I have a cube (170x170x182) of a reconstructed CT (double). I am trying to rotate the volume about it's z axis a few degrees (it is a cylinder). Everything I've looked up (imrotate, rotate, making rotation transformation matrices, etc.) and tried hasn't worked for various reasons and I'm not sure this should be such a complicated process? Any help much appreciated!

edit: when using rotate, which seems the best option, I receive error: H must contain axes children only

If you are displaying the 3D-reconstruction in a 3-D axes, like you would with slice, then you can simply change to rotation of the display with the view function:

view(12,23) % ETC

If you want to rotate the actual reconstruction, I'd go with interp3, or interpn.

It shouldn't be. imrotate() is exactly the thing to use.
