function [headmodel] = ft_transform_vol(transform, headmodel)

% FT_TRANSFORM_VOL applies a homogenous coordinate transformation to
% a structure with an EEG or MEG colume conduction model. The homogenous
% transformation matrix should be limited to a rigid-body translation
% plus rotation and a global rescaling.
%
% Use as
%   headmodel = ft_transform_vol(transform, headmodel)
