Creating several structures within another structure

Im attemtig to create two structures called nodes and elements within a larger structure called tubing. I am able to nest one struct within another, but i cant seem to do more than one. Would anyone know how to do this if at all possible in matlab or offer an alternative?

MATLAB does not limit how much nesting you can do with any container arrays.

tubing.nodes = struct('X',1);
tubing.elements = struct('cat',Inf,'hat',NaN)
