No, I'm really convinced that you do not need to create this using EVAL (or EVALIN as in your example). There is always a better solution than the evil EVAL. Do trust the FAQ and rely on hundrets or related threads in this forum, most of all consider that this method does produce problems for you already.
Therefore it is safer, simpler and more efficient to create the variable directly:
function Output = myFunc
Output.var1 = zeros(1, 6);
Now calling Laminate = myFunc from the command line create the wanted struct without dirty tricks.
