The following code creates 1x20 structure, each with four fields:
mystruct(20).x =1
mystruct(20).y =2
mystruct(20). type=3
mystruct(30).cost=4;

Read this and try some of its examples:
http://www.mathworks.com/help/matlab/matlab_prog/access-multiple-elements-of-a-nonscalar-struct-array.html
nums(1).f = 1;
nums(2).f = 2;
nums(3).f = 3;
allNums = [nums.f]
Note that you can create the complete non-scalar structure all at once using struct, which might be the easiest option for you:
S = struct('f',{1,2,3})
