This has something to do with how the struct function handles cell arrays as inputs. It's basically peeling off that cell that you are putting around A(:,1)'. Note that A(:,1)' is already a cell array, so there's normally no need to put {} around it... but the way the struct function works you need the extra { } to tell it that you want to make a scalar structure (instead of distributing each cell of A to a different index of a nonscalar structure).
