I am doing the following to convert data in a structure to an array. It seems a little clunky. Is there a better way?

a(1).data = [1 2];
a(2).data = [3 4];
a(3).data = [5 6];
a(4).data = [7 8];
data2 = cell2mat({a.data}');

You don't need to do the cell2mat conversion, you can just use vertcat.

data2 = vertcat(a(:).data);

I don't have a good way to make your definition of a.data any better.

The colon indexing is not required either. This is probably the simplest and most efficient solution:

data2 = vertcat(a.data);
