You can create a transformation matrix. I recommend using makehgtform() . Transforms for it are applied right (last) to left (first). Typically you would subtract off the center of rotation, rotate, then add back the center of rotation... except in reverse order, so something like
M = makehgtform('translate', cx, cy, cz, 'xrotate', angle, 'translate', -cx, -cy, -cz)
You would then create coordinate lists for your points, [x(:), y(:), z(:), zeros(numel(x),1] and post-multiply by M to get transformed points.
