Basically, you can't. There is no simple way. Instead of building a
cell array of scalar structs, it's better to build a non-scalar
struct:

qstr = cellfun (@quaternion, varargin);  # uniformoutput = true !

 w = horzcat (qstr.w);
 x = horzcat (qstrl.x);
 y = horzcat (qstr.y);
 z = horzcat (qstr.z);
